1. Molecular basis of spectral tuning in the newt short wavelength sensitive visual pigment

Author

Takahashi, Yusuke and Ebrey, Thomas G.

Subjects
Visual pigments, Mutagenesis -- Analysis, Hydrogen bonding -- Influence, Biological sciences, Chemistry
Abstract

The short wavelength sensitive 2 (SWS2) visual pigment of newt, Vynops pyrrhogaster spectral analysis shows that changing the amino acid residues near the the chromophore causes the pigment to exhibit blue shifts from red. Data indicate that out of the 7 residues, one residue, 91 may be involved in the regulation of color by altering a hydrogen bonding network connected to the chromophore.

7. What do colour-blind people see?

Author

Vienot, F., Brettel, H., Ott, L., Ben M'Barek, A., and Mollon, J.D.

Subjects
Visual pigments, Color blindness -- Research, Environmental issues, Science and technology, Zoology and wildlife conservation
Abstract

An algorithmic simulation using computer-controlled color displays can give normal trichromatic vision people an idea of what a dichromatic, or color-blind, person may see. The simulation is limited by the polymorphic nature of color sensing but can be used by people preparing display screens or color-coding systems as a starting point to evaluate colors used. The simulation begins with a trichromatic vision and reduces photopigments to simulate reduced color gamut. Photographs of the different visions are included.
