The difference between 0-100 and 0-255 RGB notation

  

What is the difference between 0-100 and 0-255 for RGB values?

Both the 0-100 and 0-255 sets of sRGB data represent the same sRGB standard. Notation in the 0-100 scale simply uses percentages of the 0-255 scale. To illustrate this point, let's look at a particular PANTONE Color. For this example, we have used the 0-255 sRGB values for PANTONE 602 C taken from the PANTONE color bridge, as follows:

sRGB 0-255: 237-233-140.

To calculate the 0-100 value, simply use the absolute value of the decimal equivalent of the percentage of 255 contained in the 0-255 value, as follows:

R 237 = 237/255 = .929 rounded to .93; Absolute value of .93 = 93

G 235 = 237/255 = .909 rounded to .91; Absolute value of .91 = 91

B 140 = 140/255 = .549 rounded to .55; Absolute value of .55 = 55.

The resulting 0-100 value is 93-91-55.

We hope that you find this explanation helpful.
