Public summary

On Linux, HTMLViewer can render HTML colours with the red and blue channels exchanged. For example, a requested yellow background (#FFFF00) appears cyan (#00FFFF) inside HTMLViewer, while the same colour renders correctly in ordinary Objo controls such as Canvas. Valid HTML and CSS should retain their specified colours.
