Color components whose colorspace could not be identified, kept in full.
Annotation colors are decoded by counting components — one is DeviceGray,
three DeviceRGB, four DeviceCMYK. Any other count lands here rather than being
guessed at or discarded. The values follow "Component range" in
PdfElixide.Color.
