Paint Programs & Color Matching

Posted by Clarissa on December 07, 1999 at 00:23:51:

I had a brainstorm today (if you smell smoke, that will be me ...)

I have a couple of paint programs which clearly identify the numerical values for the 3 colors which make up each individual color we see on our computer screens. Those three colors, of course, are RED, GREEN & BLUE. When "mixing" colors on-screen, the "values" for BLACK are R=0, G=0, and B=0. At the other extreme, the "values" for WHITE are R=255, G=255, and B=255. A third example is YELLOW, which is represented by R=255, G=255 and B=0. If you have such a utility on your paint program, play with it -- very interesting stuff.

The reason I bring this up is that I was WONDERING . . . . could we better predict the basic tail-color results of our precious Guppies if we looked at the RGB values of each color involved? I was first pushed in this direction when a cross-breeding of Charcoal Deltas X Pewter Tuxedos yielded the Plum Crescent color you see in the Gallery. Both the Charcoals and the Pewters were breeding true when I tried the cross. Also, as most of you know by now, the Charcoals are derived from the darkest red of the AZ Red-Tail stock. And the Pewters were bred down from the original AZ "Blue" (cyan, really) tuxedos. That means that the red and blue necessary to make purple (regardless of shade) were present, but suppressed, right? I think what I am suggesting is that if I looked at the ancestry of the Pewters & Charcoals -- first removing the black/grey "overlay" thing -- I might see a correlation between the plum color and the combined values for RED & BLUE in the color scale.

Stop me if I've gone headlong off the deep-end, here. I'm not very good at making sense of this stuff -- mostly I just enjoy the breeding process and the rewards of "new" colors to look at :-) WHICH, btw, there will be more of for you all to enjoy very soon. Watch the Gallery!
