How about a color picker in AI2 like this one without using gradient calculations?




I got bored of having to move three sliders to achieve the color I want. I like how you select colors with the hue color picker in Photoshop and I realized that some areas are always the same, and only the top right corner changes when selecting a different color in the spectrum palette.
So I tried a couple of things until it worked just like I wanted. There's a lot of things that can be added, but the basic picker works just fine.
This image explains how I did it. It's simpler than it looks.

Thank you Italo for your great color picker example.
I now used it to demonstrate the new color blocks of my tools extension https://puravidaapps.com/tools.php
Thank you Klaus for being the sponsor of these blocks.
