Paletton: An Interactive Online Color Schemer

Choosing and identifying color schemes is a click-and-drag away. Paletton's interactive online color scheme generator features a range of color schemes and options. It also has a simulator for several types of color-blindness so you can choose colors that work together no matter the viewer's perception.

Paletton's Colorpedia and Color Schemes pages are good resources for your Color Theory worksheet.

This type of interactive color schemer can be utilized in the other direction too, giving those with color-vision impairment the ability to see relationships of colors on an interactive color wheel and choose colors using RGB hex numbers.
