.~ With merging colors or patterns (e.g., Maxwell disc)
DEFINITION
Classification: 356/403
With merging colors or patterns (e.g., Maxwell disc):
(under subclass 402) Subject matter which includes a plurality of different colored light sources or reflective standards, and means to optically or mechanically rotate the light source or the standards so that the optical or mechanical rotation causes the sources or standards of different colors to blend together to produce a visual sensation of another color, shade, or tint so that the merged color can be visual compared simultaneously with an unknown light or color sample.
(1) Note. The mechanically rotating standards known as "Maxwell's Discs" are included in this subclass.
