I am new to Illustrator. I am just finding this color panel really hard to use. How do you pick a gray color from that spectrum. Before Illustrator, I used Coreldraw a lot, where there is no spectrum but easy to use color well (or color picker!) in which you can easily choose colors. I just hate the spectrum view, is there any way to replace it with color picker?
Well. Corel Draw indeed has a lot of color representations models. They have RGB cube, CMY Cube, HSB, Tone...
And I agree that that particular one you are showing has no sense and it is useless, and as far as I know, there is no way to change it. Just play with the sliders or use the Internal color picker. :o(
