Blue Is the Colour (song) of the Norwegian team Molde FK also use a variant of a song, where the title ("Blått er vår farge") directly translates to "Blue is our colour". The rest of the refrain is somehow altered, however. An adapted version called "Green is the Colour" is the official fight song of the Saskatchewan Roughriders of the Canadian Football League (Canadian football, not soccer.) This should not be confused with the Pink Floyd song "Green Is the Colour". The song was used as the basis for a campaign record used by the successful Conservative campaign in the 1979 general election. The song
Evolution of human colour vision hypothesized that T285A was one of the first two mutations because absolute max values would be between 532-538 which is close to the absolute value found in human middle wavelength opsins. Normal human trichromats require a mixture of three primary colours for every day colour vision. Protanopes, deuteranopes and tritanopes are all dichromats, meaning they use a mixture of two primary colours to match any specific colour that they see. Thus, they are missing one of the three wavelength sensitive cones. Trichromats with all three cone pigments intact can generally see minimum wavelength differences between <1 and <3 for wavelengths
