My LG Dare Drawing Pad application offers me a rainbow tool, and its color range is limited. No dark green, for example. Why is that? So I decided to take a look at the colors, and math solved my problem. Here's what the rainbow tool looks like as you apply it. Pretty. And as I've discovered, a way to get more colors from the 6-color palette that the Dare offers. But why these colors? Here's a breakdown of the individual colors in the rainbow, with the hex and RGB value underneath each color: Here are the hex values - notice the pattern: F0F F08 F00 F80 FF0 8F0 0F0 0F8 0FF 08F 00F 80FThat's the math of it. In hex values, each character is an color value. Red. Green. Blue. In that order. 0 = No color 8 = Half-Color F = Full Color And so it steps through, color to color, smoothly. Rainbow. The reason I did this is to see if it's possible for the drawing pad application to render any color possible. Dark green? Gray? And what I learned is yes. From 0 to F, it can step through the full range. This is like window shopping. So close to a palette that would allow me to get full art rendering. |
