  1. Send me an e-mail and I can send you the THREE versions of the same color as applied to a Zero... flash...gray tungsten light: brown daylight: gray-GREEN Metamerism ... Cheers, David Aiken PearlHarborHistory AT Hotmail DOT com
  2. NOW take it outside in the sunshine to see how the metamerism reacts...
  3. Masuyama vs Toyoshima?: The question was raised: "Is that possible that BII-124 piloted by Matsuyama over Pearl Harbor and BII-124 crashed by Toyoshima are two different aircraft?" Matsuyama was training Toyoshima to be a Shotaicho...and lost his own aircraft that day. Of interest, HIRYU Zeros had ROYAL BLUE (BLUE ANGEL BLUE) stripes...and in preparation for the Indian Ocean action, SORYU received new Zeros which were painted with MEDIUM BLUE stripes. Check the differences at: Ceylon Raid HTH, David Aiken
  4. Aloha All, That I3 khaki color on D3As for "Pearl Harbor" should be limited to the Fifth CV Division (Shokaku and Zuikaku). The D3As in the first and second CV Division (Akagi, Kaga, Soryu, Hiryu) were gray-green. HTH, David Aiken
  5. Aloha All, The many sensei have repeatedly stated that the Hairyokushoku (gray-green) is the Zero color. These men are those who worked with the various Japanese paint releases of that color...thus I only repeat my teachers. Read carefully the NEW data on the recently found IJN color swatches at: My link Having seen J3 (made of black and white) on the lower surface of the N1K1 in 1975, I was seeing what I expected to see on the Zero (with my meager 1975 era knowledge). When I viewed the samples of the Zero and RUFE...I was taken aback by the gray-GREEN of the rubbed samples (to get rid of any residual chalking). My sensei began to assure me of the facts. The latest color discoverys are from Japan. Several Japanese researchers made a concerted task to locate color documents with great success. Three Japanese Navy documents and a IJA document have been located thus far. The first document published was Feb 1942 IJN Document Number '0266', a test of variety of colors applied to the famous Zero. A large amount of discussion began, yet the conclusion was that more searching was required. The next document located and GAKKEN magazine printed was an April 1945 IJN document number '8609' and the number system was drastically different than '0266' for the same color name. Digging continued. and TWO copies of the November 1938 IJN document [April 1942 revision] “Temporary Specification No.117 Additional Volume†were located. This truely laid out the colors used in WWII and the other documents (above) helped to show some changes as the war progressed. Satoshi Kimura, the son of the late Tadao Kimura (pilot of Zero AI-101 at Pearl Harbor), wrote more about the history of Japanese color (This is a machine translation): My link Uniquely, in October 1941, the orders came down for VALs and KATEs of the Kido Butai to received camouflage. At that moment, these VALs and KATEs were in NMF, with silver painted on the fabric surfaces. Most had red lacquer tails. Japanese witnesses recall that this painting had to be worked around the training schedule. KATE and VAL types were training at various airfields. Paint stocks at each of the bases were used to paint both Nakajima aircraft and Aichi aircraft. Most fields had only gray-green paint in enough quanity, then those aircraft got gray-green...while a few fields had only gloss 'Tsuchi' (earth, mud) 'iro' (color) called 'I3'. Thus you may understand there was little uniformity between aircraft carriers. Of interest, R. Watanabe (in his cited article) asssured that this "I3" was used for a short while as a undercoat on Nakajima A6M2 and A6M2-N with the gray-green as final coat. My link Sidnei Maneta has nice artwork for 'Pearl Harbor' and other CV borne actions: My link Tamiya produced this 灰緑色 'Hairyokushoku' [literally 'gray-green'] for their 1/32 Zero 21 and 'unsaturated' (lightened) the color for use on 1/32 and 1/48 scale miniatures. Sweet has 'unsaturated' the 灰緑色 'Hairyokushoku' color even further for 1/144 scale Zeros. Cheers, David Aiken, a Director: Pearl Harbor History Associates, Inc. http://www.pearlharbor-history.org/
  6. Aloha TimC, One of my sensei, Kenji Miyazaki, sent the nice detail photo of the Imperial War Museum Nakajima A6M5 showing the GRAY lower surface. This is posted at: http://japaneseaircraft.multiply.com/photos/album/2/Color-samples#photo=60 Sensei K Miyazaki and H. Fujii have teamed up in a Zero detail study that continues to open eyes in M*A*R*U magazine. One item, with which I helped, was to confirm that the RUFE continued to have the Zero 21 wingfold... Oh, no aircraft company "owned" a color. Read more about IJN color at: http://www5d.biglobe.ne.jp/~cocoro/subw117-1.htm http://www5d.biglobe.ne.jp/~cocoro/subw117-2.htm HTH, Best wishes, David Aiken
  7. Literally "Hairyokushoku" means "gray-green". Note where this color is cited in the IJN "family" of colors: The Japanese Navy color terms used in WWII are: A - Kasshoku (browns) B - Aka iro (reds) C - Ki iro (yellows) D - Midori iro (greens) E - Ao iro (blues) F - Ai iro (indigos) G - Sumire iro (violets) H - Cha iro (browns) I - Tsuchi iro (earth, mud) J - Hai iro (grays) K - Kaiseishoku(gray-blues) L - Nezumi iro (grays, "Rats-color") M - Hairyokushoku (gray-green) N - Azuki iro (browns, refers to a brown bean) O - Shiro iro (whites) P - Gin iro (silvers) Q - Kuro iro (blacks) The Hess-Ives Color System of the late 1930s was embraced by Japan's military. Recent Japanese research, led by R. Watanabe and K. Owaki, have located the rough handwritten Imperial Japanese ARMY (IJA) document with the RGB values in use. The same team has located the November 1938 Imperial Japanese NAVY (IJN) document [April 1942 revision] Temporary Specification No.117 Additional Volume swatch book: My link My link Many researchers have taken up the color study, including our own Nick Millman. One major shock was that the Hess-Ives RGB values given in that IJA document were NOT the same values as the CURRENT Hess-Ives Color System. Posted in Feb 2006 is the IJA document RGB numbers into 'swatches', as given in the current RGB system...and many of the colors are NOT within the known IJA colors: My link The 'Hairyokushoku' color term is cited in both documents. On the one hand we have the IJN swatch and on the other we have the late 1930s vintage IJA "RGB" numbers. Both documents reveal colors which perhaps may be within the RANGE of each other and perhaps in the same RANGE of sample relics. What is sought is the STANDARD and the deviation (or RANGE) of each color. While we know the STANDARD by the IJN swatch...what is the RANGE of tolerance in manufacture and the what is the RANGE of change in 'combat use'. It is quite within logic that both services ordered the same 'hairyokushoku' color from the same manufacturer and gotten the same color mixed to the same swatch and still had slightly different colors because of the BATCH differences...yet the historical problem still exists to determine what was the STANDARD RGB value for the IJN swatch and what sort of SWATCH is meant by the IJA RGB document... Nick Millman has studied hard and may have been able to juggle the Hess-Ives numbers of the late 1930s into today's system. The Japanese team members are also seeking to resolve that problem. We are listening with great patience. For the color confused: Send an e-mail address to PearlHarborHistory AT Hotmail DOT Com for a scan of a Mitsubishi A6M2 relic, a Nakajima A6M2-N relic, and an A6M3 model 22 relic: all 'hairyokushoku'. Cheers, David Aiken
  8. Yes, Gato San, More gray rather than orange....my eyes have rested and am in peace! Thank you! Cheers, David
  9. Ahhh, so! Gato san, Perhaps a photo under natural light would help in the understanding. Send me a scan... Thank you so much! Cheers, David Aiken PearlHarborHistory AT Hotmail dot com
  10. Aloha All, For the color confused: Send an e-mail address to PearlHarborHistory AT Hotmail DOT Com for a scan of a Mitsubishi and a Nakajima sample. Cheers, David Aiken

    All green A6M2b

    Hi John, Mitsubishi had a "flight restricted" serial block with the dangled aileron balance...not Nakajima...and that external balance block was replaced on the production line just before Pearl Harbor, BEFORE Nakajima started production. The Zuikaku Zeros began getting non-dangles in Feb 1942; Soryu got some new Zeros in late March 1942. The Nakajima spinner is LOOOONGER that the Mitsubishi spinner. HTH, David

    All green A6M2b

    Hi John, The R. Watanabe photo is a belly landed plane...the rear is somewhat higher, thus the "overall green". The drop tank *may* be artistic license? Cheers, David Aiken

    All green A6M2b

    Hi John, The 261st Kokutai (Ku) had several garishly-marked target tow A6M2bs. One of these had an over all dark green scheme. SWEET issued a 1/144 kit in that paint scheme: http://japaneseaircraft.multiply.com/photos/album/46/Sweet_Zero_144_scale_model#photo=7 See what is "out there" in 1/48th...I am unsure. Cheers, David Aiken
  14. Aloha Gato, What color of orange did you use for the overall scheme? Curious... Cheers, David
  15. Ohayo gozaimasu Gato San, The Zero 21 "V-107" was noted in the log of Saburo Sakai for early combat in the Philippines. At that time he flew with the TAINAN KOKUTAI Headquarters Buntai, thus the blue diagonal stripe. From Dec 1941 to Late March 1942 the tail codes were white with red piping. The diagonal stripe colors were like the Luftwaffe Staffel colors: White = First Buntai Red = Second Buntai Yellow = Third Buntai Blue = HQ Oh, with the move by ship to Rabaul in late March, the newer Zeros acquired had the same diagonal stripe system, but the tail codes were black. Uniquely the command stripes for the TAINAN KU were like the 3rd Kokutai in the Philippines...from Dec 41 to late March 1942. That command system changed, when at Rabaul, to a system similar to that aboard the Kido Butai. Osamu Tagaya tried to address the command stripe change in the Japanese Info Clearinghouse/"Pacific Front" in the early 1980s...which S. Nohara copied for his MODEL ART Special on the topic. This study was the start of the deeper studies continuing today. Hope this helps, David Aiken
