For the hexadecimal number system, this digit is F. For the decimal number system, this digit is 9. The first number is 0, and you count all the way up to the last digit. These 256 colors are represented as the values 0 – 255.Ĭounting is done the same way in both systems. By using a hexadecimal, or 16-bit number system, the maximum number of colors that can be displayed at any one time is 16 x 16, or 256 colors.
Note: This also explains why the highest value possible in the RGB system is 255. The 16 characters used are the numbers 0 – 9, and the letters A – F. The hexadecimal number system is a Base-16 system, meaning there are 16 unique characters used to define the numbers.
Hex color code values, in comparison, are based on the hexadecimal number system. The 10 characters used are the numbers 0 – 9. The decimal number system is a Base-10 system, meaning there are 10 unique characters used to define the numbers. RGB color code values are based on the number system we are most familiar with, the decimal number system. While none of these are likely to make a significant impact on the development process, you may find yourself wanting to switch to hex color codes at some point – so, how does one switch from an RGB color code to a hexadecimal color code? Converting RGB to Hex Color Codes
Hex color codes can also become even more compact by using only three digits for some colors, rather than the full six digits.
Every hexadecimal code is represented by a hash sign(#) or pound.
These hexadecimal values can be derived from any graphics software like Jasc Paintshop Pro, Adobe Photoshop and also advanced paintbrush.
The Red color specified by the first two digits value which is “RR”, the green color occupies its place as the next two-digit value which is “GG” and remaining are blue color whose value is “BB”. The Hexadecimal is a six-digit representation of the color.
