What is color range?

Question

Hi. Can you please tell me what color range is?
Is that the similarity or the closest color of a color?
For example "Yellow" So the color range of a yellow is orange or red? or might be light yellow?

Answer 1

"Color range" is not any kind of technical term. It could mean just about anything (or nothing). You might have it confused with "color gamut," a semi-technical term popularly tossed around these days having to do with so-called "color managment" (calibration). Color gamut refers to the theoretical set or range of colors that can be produced in a particular "color space" or "color model" (CMYK, RGB), or process (device, printing method).
The main point of it is that, for example, there are many colors that an additive color model (RGB; a system that glows--generates its own light) can display that cannot be even closely simulated by a subtractive color model (CMYK; a system which merely reflects the light that falls upon it and which is completely dependent upon the pigments used). So because each device involved in graphics has its own "color gamut" a system is used to translate the color values called for in one device to the "nearest match" or "most approprite" that can be produced in another. There are, of course, various arguments and technical considerations which present multiple algorithms for doing that.
Pantone is a proprietary commercial brand name. It's a company that originally produced spot-color inks for offset printing, and a "matching system" for consistently mixing them, dating back to long before graphics computers.
CMYK is an abreviation for Cyan, Magenta, Yellow, Key (Black); the four ink colors used in "process color" printing. You probably remember from childhood the concept of "primary colors" (red, blue, yellow) being able to mix "any other" color (red and yellow for orange; yellow and blue for green; red and blue for purple). Well, just think of CMYK as the more accurate, formalized, standardized "primary colors" used in full-color commercial printing.
It's not really about "Pantone and CMYK"; it's about spot-color versus process-color. Do a Google for that. There is so much material out there about this, it's a wonder there is still so much confusion about it.
