Cute decorative scissors, cutting through your code.

Colours in NCurses

I decided to do some experimentation with how the colours defined in ncurses are actually displayed in terminals, what the effects are of combining these colours with other attributes, and how colour schemes of a terminal can affect the displayed colours. To this end I wrote a small c file and ran it in different terminals and different configurations. Note that only the 8 basic NCurses colours are tested, the more flexible init_color() function is not used.

Source code: nccolour.c (syntax highlighed version)
