A Brief Look at Color Models and Color Space
Color models are a way of describing colors in a numerical form. This is achieved by placing values to three or four colors and by adding or subtracting from each value altering the colors. Our most commonly used and well-known color models are RGB and CMYK. Color space is when you take a color model and define what conditions the color is going to be viewed at.
A very good example of what a color space is, lies in sRGB (Standard RGB) which was the collaborative effort of Hewlett-Packard and Microsoft for use on the Internet. sRGB took the standard RGB color model and applied gamma correction, to match it to what CRT monitors were transferring at the time, allowing for colors to be accurately represented over the Internet.
Both color models and color space are representable in three dimensional space. Color models, like RGB for example, take each color and makes it an axis on the graph. Color space on the other hand represents the color model as hue and the other two axis as saturation and brightness, which ends up giving a lot more options for color picking.
In this HSV color notation, we will explore what HSV color space is. How it has been used and how it has paved the way for more robust and modern systems of color picking in image editing software.
