▲ ▼ Colors look different according to the browser
Colors are displayed differently in each browser. The reasons are explained in detail by Matthew Szatmary, In summary - browsers and standards are a mess.
During development and video production I have to test in different browsers for adjusting to this and it consumes lot of effort.
I feel there is a need-gap in solutions for testing color accuracy across browsers.
A browser extension which lets us test colors like how responsive design test for different screen size works in browser can help address this.
