Abstract:
The use of colour mapping is fundamental to visualisation research. It
acts as an additional layer beyond rendering in the spatial dimensions
and provides a link between values in any dataset. When designing and
building visualisation research software, the process of creating and
managing a colour mapping system can be time-consuming and complex.
Existing alternatives offer niche features and require complex
dependencies or installations. We present Spectrum; an open source colour
map management library that is developer friendly with no installation
required, and that offers a wide variety of features for the majority of
use cases. We demonstrate the utility of the library through simple
snippets of code and a number of examples which illustrate its ease of
use and functionality, as well as a video demonstrating the installation
and use of the library in under two minutes. It is a very valuable
jump-start tool for developers and researchers who need to focus on other
tasks.
