High. For example looking at my colour wheel in the photograph below you can see that yellow and blue have a high contrast of hue because of their positioning.
Low. Similar colours - cold colours appear to be more distant whereas warmer colours appear to be closer.
High. The biggest contrast of tint & shade is black & white, one is high in value whereas the other is low in value.
The contrast of hue is higher due to the colours place on the wheel. (Green & Purple.)
High. A set of colours with different saturations set against a grey background can be interpreted as transparency.
Low. The colours appear more merged.
The lighter tones of colour represent the low contrast of saturation with more similarity to their opposite than the darker colours...
as you can see the grapes look darker as the colours get darker , however the grapes are all the same colour.
