My users will need to be able to choose colors for elements in my data display. There apparently is no standard Metro ChooseColor dialog so I need to create one. The problem I have with most of the designs I've seen on the web so far are that they use simple
RGB or HSL/HSV sliders. These are difficult to use with touch if you want to have any sort of precision when positioning the slider pointer (fingertips are huge in terms of pixels). The pointer can jump around, etc. and a inadvertent tap
can move the pointer a large distance. In addition, the slider would need to be large to accomodate a wide range of values. Not good.
What I want to do is sort of "invert" the slider concept. Instead of moving a pointer along a fixed axis, I want to fix the pointer and have users move the "data" underneath it. The data in this case would be H, S, and L. Optimally, the H
would be a "roller" that is continuous across 360°. S and L would be straight linear from a minimum to maximum. Only a small portion of the full range of each value would be visible at any given time, so this would allow me to use high precision ranges without
taking up a large amount of screen space.
What Metro control would be best to use as a basis for implementing this design?
Thanks
