   These LED sign boards form various colors by combining small R,G,B LEDs. If I look through the edges of my glasses for myopia which has high refraction, the pink letters will split up into blue and red letters slightly displaced (higher the frequency, more the refraction). The yellow letters split into red and green. The white borders split into red, blue and green lines! https://social.systemreboot.net/attachment/69010
