Is it possible to form a gradient from a corporate identity if it contains only solid colors?

Question

Working with color

Good day to all.
It is difficult to form a question in Google, so I thought it would be faster to ask.
In general, I draw applications for a company, their corporate identity consists of solid colors.

I wanted to ask experienced people if there are rules that allow or do not allow making a gradient from existing colors, for example, blue, orange, green, etc.

Answer 1

So do it. If the customer likes it, then so be it. No, you will think of options. As I understand it, you tried and you are jarred by this option?
