At ourpastimes.com, we are a creative team of product designers, engineers, and data scientists who want to make the internet a better place. We have poured over color theory, the math is tougher than you think, and built a showcase for color combinations.

We started by building a great virtual color mixer. We hope everyone has seen a color wheel. Personally, I loved the color wheel in my art classroom growing up. The acrylic paints like Titanium White, Burnt sienna, Dioxazine Purple make combining colors visceral and our color mixer virtually offers that visceral feeling of color mixing paints. Use our color mixer to build your next color scheme!

The color wheel pickers showcase 12 main colors. The three primary colors are red, green, and blue. When combined together, the primary colors create pure white light. Secondary colors result from mixing two primary colors:

  • Red and Green make Yellow.
  • Green and Blue make Cyan.
  • Blue and Red make Magenta .

Combining a secondary color and a primary color yields tertiary colors. There are six tertiary colors. The six color names are orange, chartreuse green, spring green, azure, violet and rose. Colors continue to expand, for example, halfway between blue and violet is indigo, color code #4B0082, and violet is halfway between blue and purple.

So, the color wheel includes twelve main colors: red, orange, yellow, chartreuse green, green, spring green, cyan, azure, blue, violet, magenta, and rose.

But how do you mix paint color? To mix acrylic paint to make gold you mix in a small quantity of brown paint (approximately one part brown to 10 parts yellow). Our color mixer is expert at mixing color by parts. Adjust the color levels with an easy toggle and we handle the math to generate the resulting hex code, RGB and HSL.

Included in our color pages are color palettes, we generate color combinations between three and six colors. We call each different color mixture “palette variances.” Each color palette variance includes eighteen color mixes with HEX code displayed.

A third component we provide on this page is color shades. For example, shades of Cobalt Blue include Blue Hour, Ua Blue, Wing Commander, Blue (Pantone), Dark Galaxy, Jacuzzi, Honolulu Blue, Zaffre, Sapphire (Crayola), Celadon Blue, Cerulean, and Corfu Waters. We offer nine tints and shades for each color. A color shade is found by adjusting the color saturation to find a darker hue. A color tint is a lighter color. For example, pink is a tint of red.
