What is the RGB code for light blue?

Light blue is a calming, tranquil color that evokes feelings of relaxation, peace, and openness. It represents optimism, clarity, and freshness. In web design, light blue is commonly used for backgrounds, headers, and buttons. As a versatile secondary color, light blue works well when paired with a variety of different hues. But what exactly is the RGB code needed to produce this soothing shade of blue?

Understanding RGB Color Codes

RGB stands for red, green, and blue – the three primary colors used in web design. By mixing different intensities of these three colors, any other color can be created. RGB values are expressed on a scale from 0 to 255, with 0 being the lowest intensity and 255 being full intensity of that color. The RGB code is written as (R, G, B) with each of the three values separated by commas.

For example, bright red would have an RGB value of (255, 0, 0) – the red is at full intensity, while green and blue are turned off. White would be (255, 255, 255) with full intensities of all three colors, while black is the absence of all light at (0, 0, 0). Gray shades are created by equal intensities of red, green and blue.

To make light blue, you need some mixture of low to medium intensities of red and green combined with a high intensity of blue. But what exact RGB values make the perfect light blue?

RGB Code for Light Blue

There are a few common RGB values used to represent various shades of light blue:

RGB Code Color Name
(173,216,230) Light Blue
(135,206,235) Sky Blue
(176,226,255) Light Cyan
(230,230,250) Ghost White

As you can see, light blue RGB values often have high blue values around 200-255, with green values ranging from 135 to 230 and red values under 200. Adjusting these values produces shades from a deeper sky blue to a pale icy blue.

Some examples of how these RGB codes render on screen:

This is Light Blue (173,216,230)

This is Sky Blue (135,206,235)

This is Light Cyan (176,226,255)

This is Ghost White (230,230,250)

As you can see, small variations in the RGB values can create distinctly different light blue hues. So what is the best RGB code to use for your needs?

Choosing the Right Light Blue RGB Values

When selecting a light blue RGB code, consider the following:

  • Context – Is the blue being used for a soothing, professional look or a more vibrant, energetic feel?
  • Accessibility – Lighter blues tend to have better contrast and accessibility for text or elements layered on top.
  • Complimentary Colors – Will the blue be paired with a warm or cool color scheme?
  • Personal Preference – Trust your own visual instincts for the shade of blue that works best.

Here are some recommended light blue RGB code selections for different uses:

  • Websites/App Design – RGB(176, 226, 255) is a pale, icy blue with great accessibility.
  • Graphics/Presentations – RGB(135, 206, 235) is a nice sky blue that stands out.
  • Documents/Writing – RGB(173, 216, 230) is soft, professional light blue.
  • Highlight Color – RGB(230, 230, 250) is a subtle, ghostly blue tint.

However, feel free to tweak the values up or down to hone in on the exact shade of light blue you need. Taking the time to test out different RGB combinations on your own designs is key.

Other Ways to Define Light Blue

RGB codes are great for digital design work, but light blue can be represented in other color systems too:

  • HEX Code – This is a six-digit code preceded by a # sign, such as #B0E0E6 for a sky blue. The hex values define the RGB values in a more condensed format.
  • HSL – The Hue, Saturation, and Lightness model allows you to adjust the exact shade.
  • CMYK – The percentage mix of Cyan, Magenta, Yellow, and Black inks.
  • Pantone – A proprietary color matching system used for printing.

Many design programs allow you to input the color in any of these formats or convert between them. But RGB is the native digital format that will be displayed on any web or device screens.

Finding Light Blue RGB Codes

If you don’t know the exact light blue RGB values you want, here are some helpful resources:

  • Color Picker – Built into most design apps and websites, these allow you to select any color visually.
  • Online Databases – Major sites like W3Schools have huge databases of color codes you can browse.
  • Image Extraction – Use a tool to upload an image and extract the RGB code from a certain pixel.
  • Saves Palettes – Many programs let you save and reuse custom color palettes for consistency.

Taking advantage of these tools makes it easy to identify that perfect light blue RGB value for your project’s needs.


With its soothing, professional appeal, light blue is a versatile color choice for designs and websites. By leveraging the right RGB color codes, you can precisely define light blue shades that evoke beauty, clarity, and openness. Aim for RGB values in the range of 130-230 for red, 135-235 for green, and 200-255 for blue. And don’t be afraid to tweak the mix until you find your ideal tint of light blue.

So the next time you want to incorporate this peaceful, ethereal hue, you’ll know exactly what RGB code to use to produce the light blue look you desire.
