| /* | ||
| * color palette. made by LeeEndl | ||
| * goal is to make color blending legible by english readers. | ||
| * | ||
| * though it is incomplete my goal is to merge primary colors (RGB scheme) using math operators. e.g. red() + blue() -> outcome: purple. | ||
| * and yes. this will also work with subtraction. (red() + blue()) - blue() -> outcome: red. | ||
| * ultimatly this should in thoery work for more complex equations. e.g. ({0}, {0}, {0}) + blue() - (255 / 6) -> outcome: black-blue (dark blue) | ||
| * | | ||
| * ---> nullfying all colors is black. TODO: make more legible like black() | ||
