Don't mix red and green. Imagine when we wear a red shirt or green pants instead. Maybe you think that you are crazy or moderate stress. But the fact, Cameroon soccer team uniforms are also a mixture of green and red. It's okay? So, what you think if sky's color is green and tree's color is red? Is it strange? No! Don't think anything when you select colors, just select what you want. Sky's color is your heart color.
