COLOR COMBINATIONS AFFECT SIZE AND PROPORTION

One thing to keep in mind when choosing color combinations is how different colors, and the balance between the colors themselves, affect how we perceive them. For example: Take a yellow square and place it over a white background. Now, take the same size square and place it over a black background. The square on the black background will appear to be smaller, even though the squares are exactly the same size. It's just how we perceive the color combination together. Remember that darker colors tend to look heavier and may overpower lighter colors. Along the same lines, when you place white text or reverse text over a black background, the text appears bold. It's one of those funky eyes-playing-tricks-on-you sort of things.
