This is a color reference I made for my fursona, Mike Vulpesian. White is for hope/motivation, blue is for peace/tranquility, and red is for love/passion.

"My wings are white, for they shall sail upon the winds of hope. My muzzle is white for I shall only utter words of hope. My digits are white for I shall use them to inspire hope.
My belly fur and life lines are blue for I shall hold peace within my core. My paw pads are blue for I shall always offer my paw in peace. My ear tips and tail tip are blue for I shall bring peace to those before and behind me. My hair is long and blue for I shall rebel against those who defy peace. My tongue is blue for it shall be used to promote peace.
My fur is red for it is love I choose as my passion."
