Translation of "cone" into Icelandic

5.5. In additive colour mixture, two or more lights are mixed. Adding a light that looks blue to a light that looks yellow will produce a light that looks white (if we pick the right blue and yellow). In subtractive colour mixture, the filters, paints, or other pigments that absorb some wavelengths and reflect others are mixed. Mixing a typical blue paint and a typical yellow paint will subtract most long and short wavelengths from the light reflected by the mixture, and the result will look green. 5.6. Colour blindness is typically caused by the congenital absence or abnormality of one cone type—usually the L- or M-cone, usually in males. Most colourblind individuals are not completely blind to differences in wavelength. Rather, their colour perception is based on the outputs of two cone types instead of the normal three.

5.7. A single type of cone cannot be used, by itself, to discriminate between wavelengths of light. To enable discrimination, information from the three cones is combined to form three cone-opponent processes. In the first, cones sensitive to long wavelengths (L-cones) are pitted against medium wavelength (M9 cones to create an L – M process that is roughly sensitive to the redness or greenness of a region. In the second cone-opponent process that is roughly sensitive to the redness or greenness of a region. In the second cone-opponent process, L- and M-cones are pitted against short-wavelength (S) cones to create an (L + M) – S process roughly sensitive to the overall brightness of a region.
