“There are many different shades and values of the primary color that we call RED: Cadmium Red ( light, medium, and deep ), Scarlet, Carmine, Quinacridone Rose, Alizerin Crimson, Vermilion, and Opera Rose, to name but a few.They’re ALL reds, but they’re also all different.”
A shade of a color is the SAME color. It is just darker due to the addition of black.

Part of the problem here is when we use words loosely. For example, I don’t really know what you mean by shade.
Technically a shade is a colour produced when mixed a pure colour with black.
But some people use shade as a synonym for colour. And some people use shade as a synonym for hue. And some people use hue as a synonym for colour.
But, in short, when we mix two colours we don’t only get one colour, we get a range of colours depending on the proportion in which we mix the two colours.
I'm not about to tell you with whom I studied, when I was in college, because you can easily find out all about him and where he lived, once he came to America and where he was THE HEAD OF THE ART DEPARTMENT ( two different schools ), which will give you a clue to personal info about me. But...he was very famous, received many different awards in his lifetime,and was awarded prestigious membership positions in several highly regarded artists' organizations.
Here's just ONE example for you to mull over and finally digest: Daniel Smith is a maker of artist grade, quality watercolor paints, their color ROSE OF ULTRAMARINE is in the purple family, is made from TWO different pigments ( PB29 and PV19 ), and is a medium value of purple. PB29 translates into BLUE29, PV19 is a shade of PURPLE; NEITHER contains a pigment that makes black! The numbers that follow the letters, is a description of the one pigment that makes a certain color shade.
The MOST expensive paints are made of a SINGLE PIGMENT and hand poured. And yes, I have an Italian set that contains ONLY single pigment paints! WHY? Because one gets a cleaner, more true color when mixing this kind of paint, BUT, one is still able to get "clean" ( not muddy ) mixes, when using a double pigment paint. And most people who look at a painting done with double pigment paints really won't be able to tell the difference, as long as we're talking about the top quality of artist grade paints.
