Comment Type: technical
Summary of Issue: 1.4.3 - 5:1 too high
Comment (Including rationale for any proposed change):
contrast ratio of 5:1 is quite challenging for designers, you canĀ“t change the corporate identity of your clients for instance...

contrast control should be a browser feature, easier to use and find than it is now.

regarding: reference in understanding wcag doc to typical visual acuity of elders at roughly age 80: those elders might need some assistive technology.


as the life expectancy in most countries of the world is still below 80, designers might get the impression they have to fulfill the needs of users, that are on the average dead already.

Proposed Change:
contrast ratio of at least 4:1
