## How to convert RGB to hex color

How to convert from RGB color to hexadecimal color code.

### RGB color

The RGB color is a combination of Red, Green and Blue colors:

(R, G, B)

The red, green and blue use 8 bits each, which have integer values from 0 to 255.

So the number of colors that can be generated is:

256×256×256 = 16777216 = 100000016

### Hex color code

Hex color code is a 6 digits hexadecimal (base 16) number:

RRGGBB16

The 2 left digits represent the red color.

The 2 middle digits represent the green color.

The 2 right digits represent the blue color.

### RGB to hex conversion

1. Convert the red, green and blue color values from decimal to hex.
2. Concatenate the 3 hex values of the red, green and blue togather: RRGGBB.

#### Example #1

Convert red color (255,0,0) to hex color code:

R = 25510 = FF16

G = 010 = 0016

B = 010 = 0016

So the hex color code is:

Hex = FF0000

#### Example #2

Convert gold color (255,215,0) to hex color code:

R = 25510 = FF16

G = 21510 = D716

B = 010 = 0016

So the hex color code is:

Hex = FFD700
