  1. I have a minor form of Dyslexia called Dysgraphia and a word processor will not correct numerical and punctuation mistakes. My wife helps me proof read my articles before I submit them. I missed this one. Sorry for confusing you. Dave
  2. My 595A catalogue is close to fifty years old and has minor water damage so I looked up the chips online. I also compared some older online chips that I had saved. I looked up all three colors just for reference. These are the Federal Standard Chips I found from different sources and the Model Master paint chips from Testors, plus the color of the paint in the bottles. One thing I found was that the most prominent online paint chip site has the same color for FS 16440 and FS 36440. In the ‘70s when I built a S3-A I purchased the 3X5 color cards from the G.S.A. to mix my paint because
  3. Thanks to all for the info. I think I will go with backdating the F4 J kit and homemade decals. I also found some other ideas for the color of these aircraft. These are the specified colors I found from different sources for the F110-A, and F4-C, overall gloss light gray, light gray top and white bottom, Navy Gray, Air Force Gray, F.S. 16440, 16473, 36440. I always thought they were painted light gull gray over gloss white. Dave
  4. I am researching what I thought was going to be a simple project building a pair of 1/48 Air Force F110-A Spectres and an early F4-C Phantom. What is the best kit for a F110-A, and the F4 B or C? What changes, if any, need to be made to these kits to get a good representation of a F110-A or F4-C? Are there any decals available for the F110-A or early F4-C? What color was the F110-A? What color was the F4-C? I already searched Google, Wikipedia, Squadron, and Great Model. Any information would be appreciated. Dave
  5. Phil I learned from the Munsell Color System that the human eye cannot detect color hues in shades of color that are low in Saturation (chroma) or are at either end of the Brightness (Value) range. This is why there are no color chips in these ranges in the Munsell Color System. The Adobe Color Picker has no trouble seeing these colors and placing a measured value on them. Dave
  6. Phil The colors shown in the paint chips on the photo are the colors I am using on these four model Mustangs. I sent this photo to my client and he agreed that these color chips looked close to the colors in the photos. This article was an answer to some people who wanted to know the paint formulas for these colors. I don’t want to know different theories about colors and how to shift colors, I just wanted to know what color to paint different model aircraft. For me the Adobe Color Picker told me what I couldn’t see by eye, because the colors in the photo have such a low sa
  7. Richard If you had a commission to paint these four Mustangs and the client wanted the models to look like the photo, what color(s) would you paint them? I am using the best method I have found and shared it with this forum. I wish some one would just tell me what color(s) they were painted, but no one has offered. Each set of online paint chips is different, the paint in the bottles doesn’t match the manufacturers paint chips. It sure would make this a lot easier if everything was in black and white, or would it. Dave
  8. Phil I never said gray was a color. Gray is mixed with a color hue to change the shade of a color, or the saturation. The brightness is controlled by the percentage of white and black that is used to make the shade of gray. All of this applies to Adobe Photo Shop, other computer software use their own methods. Dave
  9. Rex I wished it worked as easy as Lowe’s color matcher. Because most of the Model Master colors are not a pure color hue (100%), most have a large percentage of gray, it is still trial and error mixing in the paint bottle. When I get the paint in the bottle close the color chip I printed, I spray a test sample and scan it into Photo Shop. In Photo Shop I use the picker to check the mixed paint against the paint chip. This is much easier than mixing by eye. I then determine the tinting that is needed and modify the paint mix accordingly. Again spraying a sample and repeating this
  10. Phil I am trying my best not to confuse anyone but I am learning as I am trying to show what can be done with Adobe Photo Shop. Using the Color Picker, there are only three things that I am concerned with, the Hue, Saturation, and Brightness. Once I know the hue of a color the rest is simple, the saturation is just the percentage of color hue mixed with gray. The shade of gray is determined by the percentage of black and white. That is it, with this information I can mix 3.6 million colors. I can do this either by tinting existing colors to get the correct hue, or starting from scratch
  11. Rex I have far less paint bottles than you, but I am finding more and more that the ones I have don’t match the paint chips. Using Adobe Color Picker I can scan a color chip and make a formula for almost any color chip just using primary colors, and white and black. Or I can adjust the Model Master colors by tinting them to match the color chips. Model Master 1705, 1708, and 2012 aren’t pure colors, but are from 80% to 100% saturation and are close enough to use as primary colors. If I can’t get a close match with these colors I will use Testors 1103, 1111, 1114 fo
  12. Most of the Model Master Enamel Paint colors I use to mix WWII colors have from 70% to 100% saturation (chroma). Most of the WWII color chips have a saturation (chroma) of 30% to 50%. The colors on the Mustangs that I originally mixed in 2004 looked OK on models painted for clients who wanted them to look like die cast models. Now, most people want their models to look more realistic. Now I have reduce the amount of saturation to match the paint used during WWII by adding more gray to the original colors. As seen in the photos below just reducing the saturation of color makes the models m
  13. Some one asked how to mix the paint I use for painting the four Mustangs pictured in the photo. The paint color chips are attached to the photo with arrows pointing to the areas to be painted with the colors on these chips. The paint color formulas were created in Adobe Photo Shop using the actual Model Master Enamel Paints from the bottles. The paint in the bottles might vary in color and should be compared to the paint chips when mixing is complete. To increase the saturation (chroma) of each color, reduce the percentage of gray in the formula. To reduce the saturation (chroma) of each
  14. Phil I held the book next to my monitor and the photo in the book is the same as the photo posted here. The paint chips are just the base colors for the model Once the model is weathered the colors will look closer to the photo. Dave
  15. The paint in the bottles of MM 1764 FS 34092 didn’t match the paint chip very closely. I redid the formula for the green color. The colors used for the brown and sand color are a close match. Dave
  16. I am getting ready to paint a Russian B 25 like the one shown in the photo using decals from Authentic Decal (48-49). The paint color chips are attached to the photo. The paint color formulas were created in Adobe Photo Shop using Model Master Paint Chips. The paint in the bottles might vary in color and should be compared to their paint chips. More white can be added to these formulas to make the colors lighter or more faded. Dave
  17. Reading this post and your previous post on the subject I think your methodology is flawed. First off, (as others have said) scanning photos to come up with accurate colors opens up a very large can of worms. The first thing is that you are not using a standardized light source for all of your "specimens". You don't have standardized input. Also, if you scan a photo of an airplane or piece of an airplane with some color you are interested in, what determines the specific area of color? Are you picking a specific pixel and interpolating from that? I can scan a color photo and I can then u
  18. Steve In these two photos I measured the interior colors and exterior color of a Corsair. The interior color has a hue of 150°. When compared to known colors from that period it is a close match to ANA 612/ FS 34092. The color measured on the exterior was hidden from fading and is a close match to known colors from this time, ANA 603 Sea Gray. Dave
  19. Rex I can’t make any sense of the CIE color system. The Munsell System only has 100 numbered color hues, and the chroma goes way above 100% when comparing it to the saturation used by Adobe Photo Shop. I have made color chips according to the Munsell numbers, but they aren’t as accurate as the system used in Adobe. The photo of the color picker shows the different paint numbers available HSB, RGB, Lab, and CMYK. The number in the lower left corner is the ink number. When you click the “CUSTOM†button you get another nine color measuring systems. The only numb
  20. Paint colors can be measured in Adobe Photo Shop to get the Color Hue°, and the percentages of Saturation and Brightness, ( H:S:B: ). The paint chips below are all quite close in Color Hue°. The Color (HUE) is between 198° and 208°. The SHADE of these color chips is what makes them appear so different. The SHADE of a color is determined by its SATURATION (SAT), the percentage of COLOR HUE to the percentage of GRAY. The BRIGHTNESS (BRT) of GRAY is determined by the percentage of WHITE to the percentage of BLACK. Below is the Adobe Photo Shop Color Picker, measuring a Model Master 20
  21. I found this video from Zeno's Warbirds about the 362nd FG. I couldn’t copy the video frame from Window’s Media Player to Photo Shop, so I put the video on pause and placed Adobe Photo Shop on top of it. I matched the color chip by eye to the nose of the P 47. The colors in this picture are not accurate because it is a photo of the monitor. This picture was used just to demonstrate the process. The Model Master Enamel paint mix is approximately 44% black, 28% white, with 28% MM 2012 Cobalt Blue. Dave PS My monitor is calibrated using the Adobe Photo Shop Gamma Wiza
  22. Thanks to all. It's an Accurate Miniatures B 25 A/B/C/D. Dave
