good question, i always go with a feel, it is true that i am obsessed with white black and red (it is my all time favorite combo and in many of my works) but i also a big fan of sun vibes colors like yellow and orange, i come from graphics design background so i know a lot of color matching and playing around with pallets, i play around with different colors to see the mood i get and what i hit something powerful i keep it around, i like variations to bring different vibes, sometimes i will be happy with just the black and white and sometimes i will make 20 different color moods.
