Light blue is a pale shade of blue that has become popular in recent years for its soft and calming effect. Pastel blue refers to the pastel or chalk variety of light blue that is created by adding white to the blue pigment. So while all pastel blues can be considered light blues, not all light blues are pastel. Let’s take a closer look at the characteristics of these colors to better understand their relationship.
Defining Light Blue
In basic color theory, blue is one of the three primary colors along with red and yellow. Mixing blue with white creates lighter tints of blue. Light blue sits between blue and cyan on the color wheel. It is characterized by low to moderate saturation and high brightness or lightness.
There are no strict definitions for what constitutes “light blue” but it generally refers to the paler tints of blue. Some examples of light blue colors include:
- Baby blue
- Periwinkle
- Powder blue
- Sky blue
- Azure
These colors have a brightness value of around 90-100% and saturation between 20-60%. The exact specifications may vary slightly depending on the color system used, such as RGB, CMYK, or HSL.

Defining Pastel Blue
Pastel colors get their name from pastels, which are sticks of pure powdered pigment used by artists for drawing and sketching. Mixing a pure hue with white creates the soft, pale tones characteristic of pastels.
