In order to check the perception of color choices, I'd like to be able to simulate color blindness for people with normal eyesight (me, basically).
My goal is to weaken / worsen / decrease the contrast in order to get a feeling how bad something (an advertisement, UI design etc.) is for a person with color vision deficiencies.
It should consider typical color blindness types that are medically accepted, like red-green blindness, blue weakness, blue blindness and monochromacy.
It's basically the opposite of what is requested in Screen filter for colorblind, where the goal is to improve the contrast for colorblind people.
Please suggest a gratis offline tool for Windows. Ideally it's not a Windows Store app, but something else to download and install.
I want it to work with the whole computer screen or a part of the screen. There should not be a need to make screenshots, save them, upload them or do image processing in any other way.
The application should not be specific to any program. I want to look at my Windows desktop application (Word, Paint, Photoshop), my Android emulator, any website in any browser, virtual machine etc. in almost real time (a single button click or hotkey is acceptable).
I do not need:
- a pure contrast analyzer like Color Contrast Analyzer (CCA)
I have tried:
- Color Oracle, butI can't run that outdated version of Java and I am not allowed to installed the paid version of Oracle's Java.
