>>5144965Like every other color scheme, colors have value, saturation and different hues. Not everything has to be 100% fully saturated "red" and "yellow" like you've posted in the OP. You can push and pull them in different ways to create a composition. What you're referring to as "red" and "yellow" are just one particular slice of what could be considered red or yellow. You could have a dark red with a lighter yellow, or a muted, lower value yellow with a striking, fully saturated red. You could have a red that is leaning towards magenta, you could have a yellow that is leaning towards orange, etc. etc. - all while still being considered 'red' or 'yellow'.
