Why bootstrap is using blue color as the primary color?

[rohit2sharma95]

Is there any specific reason to make the blue color (the current primary color in bootstrap) as primary

Maybe if you use any other light and a little bit of shiny color. Like Github has a green color, it is pretty nice and cool. 🤓

Blue is the default link color on the web, symbolizes stability/trust/etc, and doesn't come with too much implicit semantic value (e.g., green means success, red means danger, etc). It's a neutral-ish color to build on. Hope that helps!

A little historical background on "Why are links blue?" —basically, the darkest color after black in 16 colors displays— to also mention that blue is coincidently the color most perceptible by humans.

Red and green are the colours most affected by colour-vision deficiency. Almost no one has a blue deficiency. Accordingly, nearly everyone can see blue, or, more accurately, almost everyone can distinguish blue as a colour different from others. It was pure good luck that the default colour of hyperlinks is blue with underlining.

Blue is good :)
