Next step would be to show some examples related to color combinations when it comes to gradients.
One of the most important criterias when it comes to creating mixes of colors is to go with two toned gradients created with analogus colors — colors that emerge from the previous tone, i.e. yellow emerges from orange [B1].
All this can be seen in any color wheel that contains the six main colors — Red, Orange, Yellow, Green, Blue, Purple.
An example of creating contrast in gradients is by using two colors where one side uses a dark tone and another has a light color [B6].
