the lighter the center, the brighter it appears. The darker the center the dimmer it appears.
the glow part around it determines what color the light is glowing
always make the center color is the same type of color as the glow around it. Ex: red, green, blue, etc.
do not combine random colors. Ex: red center, green glow
make sure the center color is always lighter than the glow color
hope this helps
