An askew hexagon pattern made with oblong shapes and red, blue, and yellow colors with a dark colored background.

The main color, or hue, in this pattern is red, a warm tone, which makes it stand out against the cool blue outline.  The blue and red are broken up by yellow, which is also a warm color and also stands out because of the cool blue.  All of these colors work well together because they are all high value, low saturated colors.  The blue and red colors complement each other as do the yellow and blue colors.  The red and yellow colors are analogous colors, but because they broken up by the blue, they still work well together.  Since the pattern is light in color and the background is a dark color (a dark blue or black), the colors of the pattern are much more vibrant than they would be with a white background.  The colors are so muted, but the dark background gives them brightness and vibrancy.  The dark background makes a pattern that would otherwise fade into the background, stand out.
