Grayscale to RGB colorspace converter.
Grayscale is a single channel color space where pixel value ranges from 0 to 1. Zero represents black, one represent white and any value between zero & one is a gray value
RGB (Red, Green, Blue) is the most common format used in computer imaging. RGB stores individual values for red, green and blue, and hence the 3 values per pixel. A combination of these three values produces the gamut of unique colors.
The grayscale internsity of a pixel is calculated using the following formula
\(R = rFactor * intensity\)
\(G = gFactor * intensity\)
\(B = bFactor * intensity\)
