Clearly different from the carotenoid-based plumage colours studied here, the bill of the blackbird showed the strongest changes in colour expression over the year of all studied patches (compare the scale of colour variation in Figure 3).
Because there is no way to rank coat colour differences on a presumed scale of colour, we chose a binary definition of coat colour, where dogs classified as white were given a score of 1.0 and all other colour combinations (e.g., tri colour, tan) were given a score of zero (0.0).
The scale of the colour gradient should be defined for each project individually, because the range of values differs from project to project.
Colours are produced when a material is scored with fine parallel lines, formed of one or more parallel thin layers, or otherwise composed of microstructures on the scale of the colour's wavelength.
In butterflies, the spots are composed of concentric rings of scales of different colours.
The combination of these enthusiasms is producing, in his 70s, some huge works on an epic scale of mind-changing colour and glory, as well as some miniatures drawn on his iPad.

The scale and colours of the interior are truly magnificent.
They carried a scale of distances and a colour-coded pattern of rhumb lines, or loxodromes (with lines of the same colour crossing the Earth's meridians at a constant angle, so that following each rhumb line maintains a constant bearing).
The peaks are coloured according to area (colour scale is shown to the right) and the top colour for the two lowest peaks for each metabolite is determined according to the colour scale of the highest peak for the same metabolite.
