RGB and HEX conversions Calculator

Given RGB = R:100, G:150B:230
Calculate hex code and hue.

Calculate Piece 1 of the Red portion:

Red Piece 1  =	Red - Red mod 16
	16

Red Piece 1  =	100 - 100 mod 16
	16

Check our modulus lesson
100 mod 16 = 4

Red Piece 1  =	100 - 4
	16

Red Piece 1  =	96
	16

Red Piece 1 = 6
In the string 0123456789ABCDEF
We use position 6 = 6

Calculate Piece 2 of the Red portion:

Red Piece 2 = Red mod 16
Red Piece 2 = 100 mod 16
Red Piece 2 = 4

In the string 0123456789ABCDEF
We use position 4 = 4

Calculate Piece 1 of the Green portion:

Green Piece 1  =	Green - Green mod 16
	16

Green Piece 1  =	150 - 150 mod 16
	16

Check our modulus lesson
150 mod 16 = 6

Green Piece 1  =	150 - 6
	16

Green Piece 1  =	144
	16

Green Piece 1 = 9
In the string 0123456789ABCDEF
We use position 9 = 9

Calculate Piece 2 of the Green portion:

Green Piece 2 = Green mod 16
Green Piece 2 = 150 mod 16
Green Piece 2 = 6

In the string 0123456789ABCDEF
We use position 6 = 6

Calculate Piece 1 of the Blue portion:

Blue Piece 1  =	Blue - Blue mod 16
	16

Blue Piece 1  =	230 - 230 mod 16
	16

Check our modulus lesson
230 mod 16 = 6

Blue Piece 1  =	230 - 6
	16

Blue Piece 1  =	224
	16

Blue Piece 1 = 14
In the string 0123456789ABCDEF
We use position 14 = E

Calculate Piece 2 of the Blue portion:

Blue Piece 2 = Blue mod 16
Blue Piece 2 = 230 mod 16
Blue Piece 2 = 6

In the string 0123456789ABCDEF
We use position 6 = 6

Our final RGB to HEX conversion is below:

R:100, G:150, B:230 → = 6 = 4 = 9 = 6 = E = 6

Calculate Hue for RGB = (100, 150, 230)

Since B > G > R, we are in the Cyan-Blue region and the formula is below:

h  =	60°(4B - 5(R) - G)
	B - R

h  =	60°(4(230) - 5(100) - 230)
	230 - 100

h  =	190
	130
