How to convert RGB to Hex
The RGB color code is a combination of Red, Green and Blue colors. (R, G, B). The red, green and blue colors have integer values from 0 to 255 and each of them uses 8 bits. Therefore, the number of colors that can be generated is;
256×256×256 = 16777216
= 100000016
The Hex color code is a 6 digits hexadecimal number of base 16. This can be expressed as; RRGGBB16.
Where;
The left 2 digits represent the red color (RR), the 2 middle digits represent the green color (GG) and the 2 right digits represent the blue color (BB).
Formula for converting RGB to hex
The first step is to convert the red, green and blue color codes from decimal to Hex code. The 3 hex values are then concentrated together; RRGGBB
Example one
Convert gold color (255, 215, 0) to hex color code:
R = 25510 = FF16
G = 21510 = D716
B = 010 = 0016
Therefore, the hex color code will be:
Hex = FFD700
Example two
Convert red color (255, 0, 0) to hex color code:
R = 25510 = FF16
G = 010 = 0016
B = 010 = 0016
Therefore, the hex color code is:
Hex = FF0000
