Color Selection for Hue?


Im working on a smartapp for set and specific color+bright+saturation for a Hue light.,

The brightness and saturation i got them from integer inputs at preferences, and for the color i use a “enum” listing color name (ie: Red, Blue, etc) that later become integer values and used to go to setHue(color).

Is there a way to nicer select the color? let say a color map where u point the exact tone u are looking and gets u back and hex for color? i saw that in tiles is possible, but dont know how to place this in a smartapp.
