This package provides a flexible dark or light colour theme designed for maximum readability in environments where most themes fall flat. Its main features are:

• dark color theme for presenting in low-light conditions;

• optional light color theme for presenting in bright ambient light;

• redefines color names red, green, blue, yellow to values that are visible when displayed by certain projectors, particularly those with a very bright green channel and dim red and blue channels. This behaviour can be optionally disabled, with the provided colours also available as OwlRed, OwlGreen, etc.
