Making a color picker style color wheel

[MarieMeyer]

I want to make a color picker style color wheel, somewhat like this, but with my own color selection:

Is there a way to do this by creating a segmented circle and then blending the colors of the segments together somehow? I want grayer colors in the center, so in fact I would have multiple segment circles of different diameters stacked on top of each other. After their interiors are blended, I would then need to blend them together radially.

Or am I going about this all wrong: should I be using lines that are gray near the center and progressively more colorful on the ends and then have Illustrator blend the space between them?

You could use:

- the blend function as you already wrote

- freeform gradients

- gradient meshes

Which one applies, depends upon the exact nature of your design. It's not clear to me, how you imagine it to be, so maybe try all of them out?

[MarieMeyer]

See how this one blends in the circular direction but also from the center outward?

[Monika Gause]

Your idea with blending lines should work for that.

[MarieMeyer]

It is a pretty vague idea, and I don't know how to execute on it. Could you explain?

Marie,

As I (mis)understand it, you can (also):

1) Create a circle of the desired size with a white Fill;

2) Create a stroked circle at half the size with the same Stroke Weight and apply the desired basic Gradient along the stroke, obviously starting and ending with the same colour;

3) Create a circle like the one in 1), only with a readial Gradient from black to white;

4) Select 2) and 3) and make an (Opacity) Mask, then adjust the Gradient Slider to obtain the desired radial colour transition.

You can use a gradient across a stroke.

This is a 130 pt circle with a 130 pt stroke.

Yes! And then overlay a circle with a radial gradient in desired grey percentage (0-100% opacity) ... if that's the look you're afterr?
