English: Colour palette adopted by climate scientist Ed Hawkins for "Warming stripes" graphic illustrating global warming. Dr. Hawkins chose the 8 most saturated reds and blues of ColorBrewer 9-class single hue palette. Creation date (below) was chosen as date of Dr. Hawkins' first wide publication of "warming stripes".
Printing is the process of adding localized or patterned color to fabrics. [2] Discharge printing involves dyeing first with dischargeable dyes; subsequently, the dyed fabric undergoes a printing process involving the application of a chemical-infused paste that effectively removes the color imparted by the dye.

Under color removal is used in process color printing. Black ink used to add details and darkness in shadowed areas is called a skeletal black . With current [ as of? ] ink technology, the total CMYK ink in the shadows refuses to stick after it reaches the dark shadows (usually above a 250% total CMYK coverage), and begins to peel off.
Domain coloring plot of the function f(x) = (x 2 − 1)(x − 2 − i) 2 / x 2 + 2 + 2i , using the structured color function described below. In complex analysis, domain coloring or a color wheel graph is a technique for visualizing complex functions by assigning a color to each point of the complex plane. By assigning points on the ...
If the grey component is replaced by black ink, the same color is being achieved by using two primaries and black. The substitution of black for the grey component is described as grey component replacement (GCR). [1] In GCR, contrary to under color removal (UCR), the CMY values that add to grey all along the tone scale can be replaced with ...
The technique has also been used for color-changing pictures, but to a much lesser extent. The development of barrier-grid technologies can also be regarded as a step towards lenticular printing , although the technique has remained after the invention of lenticular technologies as a relatively cheap and simple way to produce animated images in ...
The same algorithms may be applied to each of the red, green, and blue (or cyan, magenta, yellow, black) channels of a color image to achieve a color effect on printers such as color laser printers that can only print single color values.
