We have a repository of old icons which are flat,gradient,simple,compound icons for win32 and win64 applications(basically legacy software icons). Currently we are trying to do color accessibility for this,so these icons are accessible for visually impaired people.(luminosity and Color blindness)
How can we take this process? What tools we can use to analyze this? How to do the testing of the icon?
I tried Contrast color analyzer tool for luminosity and color blindness, most of icons I tested failed in the process,since the tool asking only for background and foreground color(Ex:Close icon in a red gradient circle,in this case foreground will be reddish orange and red,and background will be white, Most of the results are failing). How do we perform this testing and conclude and suggest icon color accessibility?
Please suggest us.
