The colour number of 777 refers to the hexadecimal colour code #777, which represents a shade of gray. Hexadecimal colour codes are 6 digit codes preceded by a pound (#) sign that are used to represent colours on digital displays. The first 2 digits represent the amount of red, the middle 2 digits represent the amount of green, and the last 2 digits represent the amount of blue in the colour.
Understanding Hexadecimal Colour Codes
Hexadecimal, or hex for short, is a numbering system that uses 16 distinct symbols (0-9 and A-F) to represent numbers. It is commonly used in computing and coding since it provides a more compact way to represent binary numbers. While we are used to using a decimal system with 10 digits (0-9), hexadecimal has 16, allowing each digit to represent a value from 0 to 15.
Hexadecimal colour codes work by specifying the levels of red, green and blue in a colour with hexadecimal digits. Each pair of digits represents a value between 00 and FF (256 decimal values). So for example, #000000 represents black (no colour), #FF0000 represents red, #00FF00 represents green, and #0000FF represents blue. Mixing different levels of red, green and blue allows over 16 million colour combinations.
The colour #777 specifically represents a shade of gray, since the red, green and blue components are equal. The value 77 in hexadecimal corresponds to 119 in decimal values. So #777 contains R:119, G:119, B:119, creating an even and medium gray colour.
