RGB Color Picker

What is RGB?

RGB stands for Red, Green, and Blue, and is a type of color model that is widely used in digital imaging and computer graphics. It works by combining different intensities of these three colors to create a wide range of colors. The intensity of each color is represented with a value from 0-255, where 0 is the lowest intensity and 255 is the highest.

RGB is an additive color model, meaning that light emitted from the display adds colors together to create a desired color. When all three colors are combined at their maximum intensity (255 each), they produce white. Conversely, when all three colors are at their lowest values (0 each) they create black. When all three values are equal, the resulting color is gray. In between these extremes lie many shades of colors which can be created by adjusting the level of red, green, or blue in the mix.

RGB 0-1, also known as Unit RGB, Float RGB, or Decimal RGB, is a variation of RGB where the values are represented as decimals between 0 and 1, where 0 is the lowest intensity and 1 is the highest.

RGB565 (or 16-bit RGB) is a color format that uses 16 bits to represent a color, with 5 bits (0-31) for the red channel, 6 bits (0-63) for the green channel, and 5 bits (0-31) for the blue channel.

What is RGBA?

RGBA stands for Red, Green, Blue, and Alpha. RGBA combines the red, green, and blue (RGB) components of a color with an additional alpha channel which determines the opacity or transparency of the color. This makes it possible to create partially transparent colors, allowing for more complex layering and designs. The alpha channel can be used to add shadows and semi-transparent overlays to enhance the look and feel of a design.

You can also pick RGBA colors with our color picker. Just use the opacity slider to change the alpha channel value and the output will change to be in RGBA format. To pick RGBA 0-1 colors, use our RGB 0-1 Color Picker and use the opacity slider to change the alpha channel value.

What is an RGB Color Picker?

An RGB Color Picker is a tool used to select specific shades of colors formed by mixing the three primary colors - red, green, and blue (RGB). It helps users mix different proportions of the primary colors to create their desired color and get the RGB color code for the color which can then be used in other applications.

How does an RGB Color Picker work?

RGB Color Pickers generally consist of three sliders - one for each primary color. The user can manipulate the value of each slider to adjust the intensity of that particular color. This way, they can combine different levels of red, green, and blue to create any specific shade or hue of a desired color. The color picker may also have another slider to change the Hue of the color and a two-dimensional area to change the Saturation and Brightness of the color. This mode (HSB) makes it much easier to fine-tune how bright or muted a particular hue appears. Adjusting the Saturation and Brightness in this way is often faster than having to manually adjust each of the three primary colors (red, green, blue) with a traditional RGB color picker.

Can I pick colors from my screen using this website?

Yes, on browsers that support the Eye Dropper API, you can click the Eye Dropper icon at the top right of the color picker to pick colors from anywhere on your screen. This feature is currently supported on Google Chrome and Microsoft Edge but not on Safari or Firefox.

What is CMYK? How is it different from RGB?

CMYK stands for Cyan, Magenta, Yellow, and Key (Black). The CMYK color model is a subtractive color model used in printing processes such as offset printing. It works in the opposite way to the RGB color model which is an additive color model used for screens and digital devices. Whereas RGB adds combinations of red, green, and blue light to create a range of colors, CMYK subtracts these from white light. The CMYK system works by absorbing or reflecting specific wavelengths of light that combine to create a specific range of colors.

How to use RGB colors in CSS?

RGB colors in CSS can be specified by using the following syntax: rgb(<red_value>, <green_value>, <blue_value>), where each of the three values is an integer ranging from 0 to 255. The value of each component determines how much of that color is included in the final color. For example, if all three values are set to 255, the result will be white; if all three values are set to 0, the result will be black. A fourth argument may be specified after the RGB components, which is an optional alpha channel value ranging from 0 (fully transparent) to 1 (fully opaque). For example, rgb(255, 0, 0, 0.5) specifies a red color with 50% opacity.

What is a Complementary Color?

Complementary colors are pairs of colors that, when combined or mixed, cancel each other out. This means that they produce a grayscale color when combined. They are located directly opposite each other on the color wheel. You can generate complementary colors in the RGB color space using our Complementary Color Generator.
