I am working on an app that displays various colors for kids to choose from. So, we'll have a red, a blue, a yellow, etc. These are not real objects, just a small image (like the one attached) that represents a color.
They are all 600x600px squares.
I have been asked to include one for Silver, one for Gold, and one for Bronze (if possible), but to make them look more "realistic" (which I take to mean they need something besides plain RGB colors).
What I'm looking for is an approach to creating "realistic" swatches for these metallic colors. I realize this is likely a very broad category, and not being fluent with graphic design, I wonder if anyone can make suggestions to approaches. I will be fumbling through this with Inkscape. Any suggestions appreciated.
