How is it possible to make color picker wheel/circle for RGB LED dimmer? Also would be good if it have light level slider too. Is there any preprogammed canvas object for this?

The color picker wheel is inserted to the canvas as a background picture and you choose the color by mouse click to any place. See fbMyColorsPickHSV and prgColorPickers. Pictures huecircle.png and huepalette.png are in the attached project in Webmaker/Images subfolder.

Slider function block is shown in other examples. All function blocks are opened, not as a library function blocks, so that you can modify them according to your needs.
