RGB to Hex Conversion
Students practice converting between RGB and hexadecimal (hex) formats. They learn about mixing primary colors in order to get the full spectrum of colors and how to average pixel values.

Red, green and blue (RGB) are the primary colors of light and it is through the use of these three colors that digital images are made. Representing pixel values in hex is a convenient way to analyze and manipulate digital images. Such operations fall under the field of digital signal processing, a sub-field of electrical engineering. Digital signal processing is important in many types of communication technologies and data transmission.
After this activity, students should be able to:
- Find the color of a specific pixel in an image.
- Convert the RGB value of a pixel to hexadecimal.
- Average a pixel's value from surrounding pixels.
- Explain how this information connects to engineering.
