    Using the random color generator

To randomly generate a color simply load this page. Press the "Pick a Random Color" button if you want the random color generator to produce another color for you. Our software uses a strong random number generator to produce the values of red, green, and blue that comprise each color. The output is the color, visualized, and its unique code in HEX, RGB and HSL.

If you want to pick more than one colour simply enter the number required in the first field. For example, to pick two random colors, enter "2". To pick three random colors, enter "3".

If using the random color wheel to generate distinct unique colors i.e. for players in a game, first input the number of players in the first field, then select an appropriate color palette. The color generator supports randomly choosing between red and blue, red and black, and black and white. Additionally you can use the 3-color wheel consisting of the three primary colors (red, yellow, blue), the 6-color wheel which has the three secondary colors (orange, green, violet) on top of these, or the 12-color wheel which contains the six tertiary ones in addition to the primary and secondary ones. Ideally, use a palette with as many colors as the number of unique ones that you need, or slightly more. The maximum supported number of unique colors is twelve, regardless from which palette they are being picked.

    What are HEX, RGB, and HSL colors?

These are various systems for presenting colors in a technical and uniquely identifiable way. Three of these are supported in our random color picker:

• HEX is just a group of six hexadecimal digits and is a representation often used in web design. For example, the HEX code for the color black is #000000 while the HEX code for a color in the purple range is #8f0f8d.
• RGB stands for "Red, Green, Blue" and mostly applies to digital displays, computer monitors, television screens and so on. A color written in RGB consists of three numbers, each signifying the amount of red, green and blue light that needs to be mixed in to produce the desired end color.
• HSL stands for "Hue, Saturation, Lightness" which is an alternative way of encoding colors. Roughly speaking, hue refers to the part of the light spectrum (0-360°), saturation to its intensity (0-1, 0-100%), and lightness to its brightness (0-1, 0-100%).

Our random color generator will output the randomly chosen color in all three systems, for your convenience.

    How many colors does the random color picker choose from?

As colour is simply visible light at a certain frequency, there are, for practical purposes, an infinite number of colors since the frequency range can be divided almost infinitely. The human eye is pretty good at what it does and can distinguish between about 10 million colors ^[1]. In theory, we could draw a random color from that infinity.

However, most modern screens and monitors can reproduce over 16 million colors and so this is also the range of colors our color generator picks between. It's virtual "color wheel" consists of 16,777,216 colors, to be precise.
