Observing a presentation that was mostly text on a white background, displayed on a projector.
- black on white - good
- green on white - terrible
- blue on white - legible, but difficult to distinguish from black
- light blue on white - ok
- cyan on white - mostly terrible
- red on white - ok
These colours were mostly all fully saturated (eg, blue #00f; cyan #0ff). I suspect that darker greens (#080) and lighter blues (#88f) would be better.
large blocks (for example, block graphics) ok in more or less any (fully saturated) colour.
