These Are Not The Only Colors

What is a Hex Code?

You will notice that a lot of colors are assigned by numbers. These are hex triplet, which is a six digit number. The numbers are represented from zero to F. Which is confusing as 0 is the lowest and F is the highest.

The numeric order would look like this:

0 - 1 - 2 - 3 - 4 - 5 - 6 -7 - 8 - 9 - A - B - C -D -E -F

Each group of two digits will represent how much of red, green, and blue. The first two digits is red, second two green, and the last two is blue.

For example:

#FF0000 is red, because there is max of red, with no green or blue.

#FFFFFF this will result in white as all values are maxed out.

#000000 would result in black as all values are zero.

Are Web Safe Colors Still Relevant?

As it is important to know what colors you are working with, using web safe colors are becoming less or a concern when design your page. As of the time of this writing most devices, mobile and desktop, now use a 24 bit colored monitor, which is more than enough to produce any color combination.
