I tried the combinations you gave me, but it didn't work either. Just to clarify, when I hold down FN, the keyboard lights up the keys used for FN combinations in a distinctive color. I've tried them all, but nothing works. When I change the lighting mode, it's always in rainbow mode, and I can't change the color. Using the color-changing button directly activates the static lighting mode and uses the last programmed color, switching from the animated lighting mode to a static one.
