Where can I find examples of "color stripe"?

Question

Design

Hello.
Silly question, but I'll ask anyway because I need to.
When we developed the concept of the site, the designer offered us a choice of vertical stripes, where corporate colors were displayed (for example, from dark green, green, beige and white). And so on for several colors. As a result, we were able to choose the color scheme that we like best. And we have already used these colors in the development of the website prototype.
Question. And where can I find such things and are they ready-made?
