Hi all, I'm trying to create a color picker for Android that looks like a minimalistic version of Gimp's. So, it has a hue slider and a rectangle with saturation/value variants of a color chosen in hue slider.

Question: what is the best way to create the rectangle?

Right now, I'm creating an 200x200 array of pixels, but it takes ~5sec to create and display rectangle with that array. And I need colors in rectangle to change whenever I change the value in hue slider...

Rectangle is bitmap, btw. Can I use color matrices on that and how? Any examples?

Thanks in advance!
