App to find available color schemes / palettes based on one color

I'm 17M, a graphic designer, and I make most of my art on an iPad. I want to create an app where, based on a single color, it will generate multiple color palettes for me to use. These color palettes will be based on different color schemes: Monochromatic, Triadic, Complementary, Complementary Triadic, Analogous, Neutral.<br><br>I want to generate the color palettes randomly until I find a scheme that I like. I want the color palettes to be displayed as random shapes, making it easy to see which colors are used in the scheme. I should be able to copy a color code with a tap, and be able to share a color palette with a tap as well.<br><br>When I go back into a color palette, I want to be able to customize it by changing the main color used, and I want the remaining colors to adapt based on the scheme, and the new main color used.<br><br>There will also be popular color palettes in the app, which you can view and copy, and the colors often go well together because they are often used in nature, and in professional graphic design projects. I also want to include a gallery where you can look at other people’s artwork created with the app, and see the color palettes they used.<br><br>I was wondering if this app idea already exists, and if not, how to go about making this app.
