let me rephrase, color doesnt necessarly make a difference. i know that generally blue is cold and yellow is warm, but saying get yellow in "x" situation is pointless because there isnt a universal scale for determining wax colors
take, for example, board side down wax. they make two all temperature waxes, one that is blue and one that is red. that right there proves the point that wax color isnt a direct correlation to temperature
