Decide on a colour from the colour wheel and create a monochromatic design by picking out the various tones, tints and shades of that one hue. For example, the hue you’ve chosen is blue. You can choose sky blue and navy to be part of that colour scheme as both colours are based on blue. For something extra, add a neutral colour like white or grey.
A triadic harmony is composed of three colours that are equidistant from each other in the colour wheel. Examples include red-yellow-blue and violet-green-orange. A good way to use a triadic harmony is to use one main colour and use the other two as accents.
Combine one or two tertiary colours with either a primary or a secondary colour. On the colour wheel, these colours must be next to each other, within a right angle. For example, if you choose blue, pick blue-green and blue-violet. The effect of this color scheme should be faint or eye-catching, depending on how you use the colors.
This color scheme is all about contrast. It is composed of two colours that are opposite each other on the color wheel - like yellow and violet. This pair of colors will serve as the main colors. This results in an energetic clash of color with the balance being tipped depending on the intensity of the colors.
