Technical Color Terms

Objects can be classified into achromatic (no color) or chromatic (having a color). For achromatic objects, they can be arranged according to lightness or value, the order of lightness is from white to gray to black.

Chromatic colors are defined by it’s hue - red, green, yellow, blue or any shades within the color spectrum. Saturation (also known as chroma) determines the degree of the color – or the ‘how much color’.



The color of an object has three attributes - hue, saturation and lightness.

We detect color difference in the order of hue first, followed by chroma and lastly lightness.







Some common color terms are:

Tint is the mixture of a color with white. Pastel is a soft delicate hue. Harmonious colors are colors close to each other in warmth or coldness.

The use of complementary color schemes are like red and green as experienced during Christmas. The use of gold on a rich blue background was a favorite of renaissance painters.

The Power Fruit

Banana peel reveals the stage of ripeness. Bananas are harvested green and at this stage the green peel is firm. As soon as the banana stem is cut from the plant, ripening starts.

  • Bananas are harvested green.
  • They sweeten as they ripen, as the banana ripens, the peel color lightens and changes to yellow.
  • During this process, the starch within the banana converts to sugar giving riper bananas their creamy, sweet taste.
Do not place bananas in your fridge, leave them on the counter is good enough. To hasten the ripening process you can place them in a brown paper bag and close it. The ethylene that's produced by the ripening process actually speeds the ripening process.

Watch the banana peel.
