Colour in generativepy
Categories: generativepy generativepy tutorial
generativepy provides several ways of defining colour values, via the colour module. Colours are stored as Color objects. For more information about computer colour in general, see the colour articles in the computer science section.
Here are the main features of generativepy colour support:
- Colour creation - you can create colours using:
- RGB values
- Grey values
- CSS named colours
- HSL values
- Transparency - all colour spaces also support transparency (alpha) values.
- Properties - you can find the properties of a colour.
- Derived colours - you can also create a new colour from an existing colour by either:
- Setting a new R, G, B, H, S, L or A value.
- Multiplying the R, G, B, H, S, L or A by a factor.
- Interpolation - you can interpolate two colours (lerping) and also create colour maps.
- Colour schemes - allow you to create reusable sets of named colours.
All colours are stored internally as RGBA colours, using floating-point values in the range 0.0 to 1.0 to represent each channel.
