Colour Selector is an application for selecting, mixing and previewing colours, intended primarily for Web developers as it deals directly in HTML hexadecimal colours. It features several colour selection and display modes, can copy and paste HTML colours, and supports drag and drop.

Colours can be selected via RGB and HSV sliders, entered as an HTML hex code, or chosen from a colour palette or a bank of favourite colour slots. Pairs of colours can be blended together to obtain an in-between colour, for if you want to adjust one colour to be more like another. Text preview is also available, to determine how text of a particular font and size will look in a particular colour, over a chosen background colour.

All the program’s settings (with the exception of the live colour copy state) are saved when the program exits, and restored again when next loaded.
