What do they mean to you? Let your ranting flow, as well. This tends to cause many a discussion IME, so I will just let it happen and hope we can still find a way to keep calm. Though, I also hope you will disobey and keep what you have to say to yourself as I tend to get very defensive.
Personally, a shade is any one tint or hue (light or dark version of a colour). A colour is strictly one basic form which can then become a shade (therefore, I count pink as a shade of red).
I absolutely hate when people call black and grey and white shades. I can see shades of black just as clearly as shades of red, blue, orange, any other colour. The shades of black are different from those of grey, too. So it bothers me when some will take my definitions above and try to use them against me by saying that there are no shades of black. A small proof I can give is that if you lightly shade in black on a piece of paper, it will show signs of remaining black. Continue shade in a spot vigorously with grey, and it still remains grey without signs of blackness. Though, this could be a perceptive thing, I deny it and stand with my belief that the so-called "shades" are colours.
Correggimi per favore (se lo sbaglio è grave, sennò non correggermi perché potrei correggermelo da solo)
