This is a colour picker!!! You can put this in your own projects too, by just backpacking the "Colour Picker" sprite (no credit needed)! To show it, constantly broadcast the "Show Colour Picker" message. The colour picker has two colour modes: HSB (Hue, Saturation, Brightness) which is what Scratch uses, or RGB (Red, Green, Blue) to change the red, gree, and blue values of the colour. To close the picker, either stop broadcasting the message, or check for the "close button" variable being greater than zero. Example in the backdrop. In code: <([close button] of [Colour Picker]) > 0>
