Hi PH fam! I have been studying on web accessibility for some time, particularly the impact of colors on a website. Going through the internet and researching, checking out tools to find out color contrast led me to an interesting observation that color contrast, although measured as a ratio and guided by WCAG 2.1 requirements, can make our websites better accessibly, the guideline itself is flawed in some aspects. Primarily, it doesn't account for the fact that all humans have a different perception of colors. And since people perceive colors differently, a single yardstick of such mathematically calculated ratios cannot accurately define the actual perceived contrast of the colors in real world ambient conditions and a graphically rich environment. I have created this tool based on the upcoming WCAG 3 APCA (Advanced Perceptual Contrast Algorithm) which sees massive improvements over the current system. Check it out and use it extensively in building your next application!
