My opinions about the currently used colors

1) All tones should be used before using shades I.E gray should appear before dark red/blue
2) Some colors/shades are too similar (light green/yellow; light red/purple) and some tones/shades are not used (black/white, brown/orange)

Supposedly current order of colors (seen from replays): blue, green, red, light blue, light green, light red, dark blue, dark green, dark red [...] (i dont know the rest)
My suggestion: blue, green, red, yellow, orange, purple, gray, light blue/teal, dark orange/brown, dark blue, dark green, dark red, black

Me likey.
