bridges.base.Color Class Reference

Detailed Description

@brief This class is used to represent colors in BRIDGES.

We use an RGBA model
to represent colors, with each component in the range 0-255. BRIDGES
also supports named colors for user convenience, but these are converted
into [RGBA] prior to transmission to the server for visualization.

<p>

Supported named colors are listed below and here: https://drafts.csswg.org/css-color-3/#svg-color
