This thread is just a basic color theory and techniques thread for those that would like some ideas and help for those that want it. There are plenty of supplementary websites that can delve deeper into the subject. I’m just giving a basic overview of it.
Starting with the color wheel.
The primary colors are red, yellow and blue. They are primary because they are colors that can not be made by mixing colors.
Secondary colors are green, orange and purple. These are created by mixing two primary colors. Red + Yellow = Orange / Yellow + Blue = Green / Red + Blue = Purple
Tertiary colors are created by mixing primary and secondary colors, which can be identified by their hyphenated name, i.e. yellow-orange, red-orange, red-purple, blue-purple, blue-green & yellow-green.
Warm and cool colors:
The color wheel is also separated by the temperature of the colors, warm and cool. Warm colors tend to advance in space while cool colors recede. Using these temperatures in your work can create atmosphere or provoke an emotion.
Tints, Shades, and Tones:
These terms are often used incorrectly, although they describe fairly simple color concepts. If a color is made lighter by adding white, the result is called a tint. If black is added, the darker version is called a shade. And if gray is added, the result is a different tone.

Color Schemes:
Complementary colors are colors that are opposite each other on the color wheel are considered to be complementary colors (example: red and green).
Analogous color schemes use colors that are next to each other on the color wheel. They usually match well and create serene and comfortable designs. These color schemes are often found in nature and are harmonious and pleasing to the eye. Make sure you have enough contrast when choosing an analogous color scheme otherwise that’ll have a washed out or flat look.
A triadic color scheme uses colors that are evenly spaced around the color wheel. Triadic color schemes tend to be quite vibrant, even if you use pale or unsaturated versions of your hues.
The rectangle or tetradic color scheme uses four colors arranged into two complementary pairs. This rich color scheme offers plenty of possibilities for variation.
The square color scheme is similar to the rectangle, but with all four colors spaced evenly around the color circle.
