I need to build a colour wheel. It has these specs:
- The user needs to be able to select a colour from it
- It should show as many colours as reasonable. The client wanted the
entire 16 million+ colour spectrum but I pointed out that at one colour
per pixel that's a 2,000 pixel square. It would be good to get thousands
of colours.
- The colours in the wheel should have a smooth transition across the wheel.
I was thinking of building the wheel in some other app and screen
capturing it and then using some arithmetic to work out the colour under
the cursor but the numbers are killing me.
Can anyone either tell me where I can find one or how I can go about
building one?
