This Hexadecimal Color-by-Number Easter Egg worksheet is a great introduction to how HTML color coding works and other basic coding skills!
Do you remember doing color-by-number activities when you were a kid? I loved following the key to color different sections of an image to reveal cool patterns or images!
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!
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!
How to Use these Hexadecimal Color-by-Number Coloring Sheets to learn Hex Color Codes
The Easter Egg sheets do not need to be printed in color, but the hexadecimal color coding key (page 3) should be printed in color – you’ll need to reference the hex code key for this activity.
Pick out markers, pencil crayons or crayons that match as closely as possible to the color legend on the coloring sheet.
Find the hex code you want to start with on the color key page. Next, match the hexadecimal code to the digit used to represent it in the Easter egg.
Fill the correct sections in with the matching color listed in the color key.
We enjoy coloring one hex color code at a time before moving on to the next. This is a great way to introduce a simple algorithm or a series of steps for completing an activity.
Once finished, you’ll have colorful Easter eggs and be more familiar with how colors are represented in hexadecimal code using the hex color system!
You can cut the Easter eggs out and use them to decorate or add them to more projects!
