i didn't say "lighter shade of blue" i said "shade of blue", also, adding white adds red, making it not cyan, so no, you're wrong.
You said in the comments of ID:3069171 that cyan was a lighter shade of blue; if that was true, blue and white would make cyan and, evidently, it doesn't.
if you add white to blue, it wouldn't make cyan, it would make a light blue, because cyan doesn't need red, also, adding white and cyan would just bleach it, so no, this isn't proof. -1
