Is it OK to grey out disabled buttons?

For a smooth and seamless experience, it's best to avoid graying out your disabled buttons. Instead, you should decrease the opacity to make it transparent. When the disabled button is transparent, users can see some semblance of the button in its enabled state.

Are disabled buttons bad for accessibility?

Bad accessibility

Sometimes disabled buttons are designed in a way that they cannot be read by a screen reader (buttons are not focusable, and hence users can't reach them with a keyboard). No need to explain that users with disabilities will face problems with such behavior.

Do screen readers read disabled buttons?

Screen readers ignore disabled controls, so screen reader users won't hear the message. Add some nearby visible help text for the button. This would work for sighted users, but not necessarily for low vision users or blind users using a screen reader.

Do disabled buttons need to pass color contrast?

The question: Do disabled buttons need to conform to colour contrast guidelines? The answer: No disabled buttons do not need to pass color contrast guidelines.
