I finished my calculator project and am passing all tests. I am not a guy with an eye for visual design (doing these certs in order but I really feel more drawn to systems/backend stuff). I’d appreciate it if anyone would take a look and give me any advice on things to clean up, sources on how to come up with good color patterns that you have found helpful, etc.
I’m no artist so I won’t be able to give you advice on color palettes, but I am into accessibility and color is definitely a consideration as far as that is concerned, so I can give you advice there. The color you are using for the equation above the answer does not have enough contrast with the gray background to be accessible. There are a ton of tools available to help you test for color contrast accessibility. One of my favorites is the WebAIM contrast checker. The contrast must be at least 4.5:1.
