16 Color Palette Test Multicolor (Diamond Hotend)

thingiverse

I wanted to see a color palette so I made one that could be printed with a diamond hotend. There's probably already one out there but I couldn't find one (not that I searched for very long). I checked the https://reprap.org/wiki/Diamond_Hotend webpage, but I didn't see the files for it. So after making it, I printed it out with Cyan, Magenta, and Yellow filaments. Well, of course not what I expected, although, I expected it would not come out as I expected, so I guess I expected correctly. The outer color pixels looked like a nice rainbow of colors! Also, try to ignore the over-extrusions. 1. Cyan = OK 2. Ocean Blue = Blue 3. Blue = Purple 4. Violet = Magenta 5. Magenta = OK 6. Raspberry = Magenta 7. Red = OK 8. Orange = OK 9. Yellow = OK 10. SpringGreen = Yellow with a hint of Green 11. Green = LightGreen 12. Turquois = LightCyan 13. CyanBrown = Gray 14. MagentaBrown = Light Magenta 15. YellowBrown = YellowGray 16. Brown = Light Brown (Beige) So about 1/3rd came out well, about another 1/3rd are usable for something else, and the last 1/3rd looked like something that was already represented (even if the thirds math doesn't work for 16 colors). I'm not using wipe towers since the diamond head only needs a couple of mm of filament to switch colors so I'm guessing that would have only helped slightly. I could have scaled up the size to double but again, I'm guessing that would not help significantly either. My colors, even though the same weights, do not match what was seen on the Diamond Hotend webpage above. This could be because I'm using opaque colors and perhaps they are using translucent colors or it could be due to variations in filament hue. So, yeah, either way, I'll need to adjust the settings/weights to try to come up with a better representation of these colors. And that's why it was good to make this color palette thing and test out the color palette. Because you don't get what you expect, you get what you inspect (I've heard that once somewhere). Of course the colors you choose when printing are up to you. I might try to test out a black and white color palette next to see if I can get good distribution of shades of gray, and then try a three color palette of black, white, and blue to see if I can get a good set of colors using one color and lighter and darker. To name a few. Of course no two filament rolls will match each other either but it probably won't be a significant change usually. Update: I have tried some more color combinations of Cyans, Magentas, and Yellows (see pic) while trying not to repeat colors already used, and uploaded a "colors" settings file here to show the settings I used. I will at some point pick the colors I like for my main color palette to use. Yeah, there's probably better ways to do this but it works. With this test, a few good colors expressed themselves such as green, blue, skin tone, and a dark color that might be good for black, and maybe a few others. Update: I changed the color palette and reprinted (I stopped it before it was finished). It looks a lot better. However, the red (bottom-left) looks a bit too orange so I might tweak that, and the purple at the bottom looks better than either purple at the top. The blue in the upper right looks too much like cyan. So yeah, I could tweak forever probably but as it is, it already looks much more reasonable.
