Red has not enough contrast

 Red text on a white background does not have enough contrast.


In other words, red text has a contrast ratio of less than 4.5:1.

I now use a darker red: 'rgb(235,0,0)'.


I check the contrast of colours with the 'Wave' tool from 'webaim.org'.

This Firefox just inverts the elements you add. The Firefox developers feel they are following the specification. Using 'invert' when there is an 'overlay' scrollbar on Chrome sometimes makes the scrollbar disappear. I am using the last version of Chrome on Windows7. I understand 'overlay' scrollbars have been removed from the latest versions of Chrome. Of course, a dark scrollbar on a black background does not make sense. So I would need to use 'color-scheme' to change the color of the scrollbar. But 'invert' does not work well with 'color-scheme'.
