out of the blue

“Hue” refers to wavelength on the wheel of spectral colors.

Any hue plus black is a “shade”. 

Navy is a shade of blue.

Any hue plus white is a “tint”. 

Pink is a tint of red.

They share the same hue based in red, 

but pink is far less saturated.

So “saturation” refers to color intensity, 

with no mixture of white. Got it?

I like Gerbera’s for their saturated color.
