Click the green flag! Bring your mouse to the top of the screen to change the sliders. These palettes are random - I guarantee you will never get the same colors twice. To do the palette I made for the thumbnail, my settings were*: Color Change: 12 Time: 1.25 Shade Change: 1000
Credit to @CaramelCloud for inspiration - I had this idea long ago but she brought the idea back to me from her project: https://scratch.mit.edu/projects/143628925/ * - Does not guarantee same colors The settings mean: Color Change - How much the color can be varied by (will go from the opposite [negative] of the number to the number itself). Time - How much time to wait between switching color/shade (in seconds). Shade Change - Same thing as color change but with the shade (brightness) of the color.
