Rainbow colormaps are among the most derided ideas in data visualization, second only to pie charts. And yet, people use them. Why? A recent paper looks at some of the reasons why they are so popular and points to research showing that they might not be so bad if used for the right tasks. There's even opportunity for interesting research in rainbow colormaps!
The rainbow colour map is not well suited to visualising data with a large dynamic range because it can compress the data and make it difficult to see small changes. Scientists have proposed a number of alternatives to the rainbow colour map, such as the jet colour map. However, the jet colour map is also problematic for many of the same reasons.
Some 15 years ago, Visualization Viewpoints published an influential article titled Rainbow Color Map (Still) Considered Harmful (Borland and Taylor, 2007). The paper argued that the "rainbow colormap's characteristics of confusing the viewer, obscuring the data and actively misleading interpretation make it a poor choice for visualization." Subsequent articles often repeat and extend.
The rainbow color map is named that way because it goes through all the rainbow's colors. The lower values are in the beep blue range and the higher values in the reds. In between it passes trough light blue green, yellow, orange It is used as a default in many visualization systems since it is easy to calculate (it is a linear interpolation between (0,0,255) and (255,0,0) in RGB color.

Figure 3. The same simulations but with a slight shift of the lower colour bar limit for (a,b) the non-uniform rainbow and (c,d) the perceptually-uniform davos colour map. Significant visual manipulation of the data results when using the rainbow colour map, while the simulation looks, for both cases, factually the same with the davos colour map. (a) The upper-mantle transition zone (enlarged.
Overview A rainbow color map is based on the order of colors in the spectrum of visible light-the same colors that appear in a rainbow. Figure 1 shows one particular form of rainbow color map. Since multiple methods exist for computing rainbow color maps, they do not all look identical, but they all feature the same general ordering of colors.
Abstract. Nowadays color in scientific visualizations is standard and extensively used to group, highlight or delineate different parts of data in visualizations. The rainbow color map (also known as jet color map) is famous for its appealing use of the full visual spectrum with impressive changes in chroma and luminance. Besides attracting attention, science has for decades criticized the.

An example of a misleading colour map is rainbow, which generally starts with blue for low values, then passing through cyan, green, yellow, orange, and finally red for high values.

Each color has a different luminance, so a color in the middle of a rainbow map, may be perceived as brighter than a color on the ends. This also has a negative effect when printing in black and white. Rainbow maps don't work well in terms of accessibility, CVD. Once you see a rainbow maps, you'll start seeing them everywhere.
However, the choice of color map can have a significant impact on a given task. For example, interpretation of "rainbow maps" have been linked to lower accuracy in mission critical applications, such as medical imaging.
