This Color by Hexadecimal Rainbow is an excellent activity to introduce hexadecimal color coding other to young kids with a recognizable and well-known object!
My kids love color-by-number activities including pixel coloring images. Color-by-number activities are a great way to introduce basic coding skills by following a key code, matching pieces and patterns to create an image, and executing an algorithm or series of steps to complete the activity!
The colors of the rainbow (ROYGBIV) are an easy way to introduce common hexadecimal colors to young kid coders.
This activity helps connect the hexadecimal code to a well known pattern, which helps to relate technology to a knowledge that is already known.
What are Hexadecimal Color Codes?
Hexadecimal color codes, or “hex” color codes, are how the colors we see in the world around us are translated into coding applications for use on websites.
Hexadecimal color values are colors that are supported in all web browsers. Every website you visit uses hex color codes!
A hexadecimal color is specified with #RRGGBB. RR (red), GG (green), and BB (blue) are hexadecimal integers between 00 and FF that identify the intensity of the color.
For example, the color aqua is #00FFFF in hexadecimal code. The hexadecimal code for aqua shows that there is 00 red used to make aqua while there is the highest intensity of blue and green used (FFFF).
Hexadecimal colors are defined by a mix of red, green, and blue. This is called the RGB color system, which consists of colors made from mixing red, green, and blue.
The RGB color system is also referred to as an “additive” system because it starts with black and color is added. Each color has 256 levels of intensity, which means that there are over 16 million hex color codes to choose from!
