Default theme: contrast

[oleq]

The default theme must be accessible, especially in terms of contrast. There's usually a kind of trade–off between an accessibility and pretty design that we must deal with.

Research needed:

• Does the new theme follow WCAG 2.0?
• Does it satisfy existing standards of CKEditor 4?
• What other resources and specifications can we use to make it even better?

Resources:

• IBM Web accessibility checklist: Use of Color.
• "The Dribbblisation of Design" – an article on Medium.

As a quick feedback, there is no doubt that we must adhere to WCAG 2 AA. So checking and research is needed.
