Shades of Blue

The color blue is an elusive one - it has a wide range, and interperatations of "blue" differs from person to person!

Blue vs Azure vs Cyan

This site includes all hues of "blue": the classic RGB blue, as well as cyan, teal, azure, and some indigo.

There's also different concentrations of "blue" - what makes a color "grayish-blue" versus a "cool gray"? I have an idea, but I don't think it's perfect, and again, varies on who you're asking.

Blues that are deemed "gray" are marked with a half moon icon.

What is Indigo anyway?

In my personal opinion, what we percieve as "blue" nowadays is actually indigo!

Colored pencils seem to agree with me on this one.

Hues tracked

This site mostly tracks the hues 170 - 240.

The key word is "mostly", because there are expections with some named "blue" colors that lean green, or warmer blues (or indigo!) that still looks like blue, but has a hue value of over 240.

Blues that are deemed outside the bounds are marked with a rainbow icon.
