Oooooh! I will probably forget and get confused again, but that explanation makes sense. Thank you!Grey doesn't exist. Lavender is every feather is same shade (whole feather). Blue is feather patterned in shades of gray or has dark/light shades on body. If Storm were black/white or black/gold, the feather pattern would be laced because feathers are edged in darker tone. Because it's shades of grey, it's just blue. Because the head is dark and body lighter, it's also blue.
One more question. Why aren’t the Roadrunners ever described as blue? This one looks pretty blue to me!
