I'm a newbie to the community and with English, but I try to explain here my question.
Now I'm working to create a web app with several buttons -and several different colors.
Their initial location is in a vertical menu (background-color: #282828
) and they can move on a white side canvas.
The problem is that they don't have the same readability.
While I'm googled to find the problem, I've read about contrast ratio, and lightness (HSL) - but also the colors with the same lightness don't have the same contrast ratio (i.e. the same readability).
So, how can I create a set/palette of color that have the same readability, contrast and feel?
I wish I explained myself.
Thank to who replies.
