sorry for late response but
if you want to add COLOR palettes, make a global variable called "palettes" or something, and give the sprites of the player the "replace color" effect, and if the player is overlapping the dresser and the up key is pressed, add 1 to palettes. if the palettes is greater than the palette limit (example:9) set value to 0. for each palette, do a compare variable and set the value to the desired number and for the actions, do set effect paremeter and for the colors, do rgbex(0,0,0) (replace the 0s with color numbers from 0-100, for 255, do rgb255(0,0,0))
will post a screenshot of this later
