Blue is a popular color that comes in many different shades and hues. When people think of blue, often a rich, deep shade comes to mind. However, blue has a vast range that includes light, pale tints as well. Determining the lightest shade of blue requires an understanding of color theory and paint mixing. We can also look to common color palette standards for guidance on the lightest blue shades. While personal preference plays a role, examining the technical qualities of different blues can provide insight into which qualify as the lightest.

Defining Light and Dark Shades of Blue
In basic color theory, tones are determined by how much black or white pigment is added to a pure hue. Adding white creates tints, while adding black makes shades. Therefore, light blues contain more white mixed in, while dark blues have more black. The more white in the blue, the lighter the tone. For example, navy blue has a lot of black and is very dark, while baby blue is lightened considerably with white.
Tint, Tone, and Shade
Specifically, a tint is the mixture of a color with white, which increases lightness, a tone is produced by adding gray, and a shade is created by mixing a color with black, which reduces lightness. So when we talk about light blue, we’re referring to tints of blue made by adding white.
How Lightness is Measured
There are a few ways to quantify the lightness or darkness of a color:
Hue
The hue refers to where the color falls on the visible spectrum of light. Blue is its own hue.
Value
The value indicates how light or dark the color is on a scale of 0 (black) to 100 (white). Lighter blues have higher values.
Saturation
Saturation measures the intensity of a hue. A highly saturated blue will be vivid, while a muted, grayish blue has low saturation.
Brightness
Brightness also describes how light or dark a color appears. It takes into account how colors interact with black. Brighter blues approach white.
So in determining the lightest blues, we are looking for hues with very high value, brightness, and lower saturation.
Common Types of Light Blue
Some well-known light blue shades include:
Baby Blue
This pale tint is named for its use in baby clothes and nurseries. It has a slightly grayish tinge.
Powder Blue
Powder blue is similar to baby blue but even lighter and cooler in tone. It is meant to mimic blue pigments in powder form.

Also called sky blue, this light cyan color is the lightest tone of pure blue and has high value and brightness.
Alice Blue
Alice blue is an even lighter, ethereal blue tint originally formulated for fancy silk and china.
Azure
This pale blue is lighter and brighter than sky blue with a hint more cyan/green.
