Colour harmonies falling under the category of related colour schemes are:
A. Analogous B. Triad C. Tetrad D. Achromatic E. Monochromatic
Choose the correct answer from the options given below:

Correct option is A

Related colour schemes are those that use colours that are adjacent or closely related on the colour wheel. These include:
· Analogous: This scheme uses colours that are next to each other on the colour wheel (e.g., red, red-orange, orange).
· Monochromatic: This scheme uses variations of one hue, such as different shades, tints, and tones of a single colour.
· Achromatic: This scheme includes black, white, and greys, and is neutral rather than based on any colour hues.
Triad and Tetrad, on the other hand, are not considered related colour schemes, as they use colours that are spaced equally or in a rectangular arrangement across the colour wheel.
Information Booster:
· Analogous colours are next to each other on the colour wheel, creating a harmonious and subtle look. For example, blue, blue-green, and green.
· Monochromatic schemes use only one colour, but vary in shade and tint (for example, different shades of blue from light to dark). It’s simple and clean, creating a soothing, unified feel.
· Achromatic colours, while lacking hues, form a neutral palette. These include black, white, and grey tones, which are used for contrast in a design but do not introduce bold colour relationships.
These three colour harmonies are related as they either use similar hues or shades of one hue, making them harmonious and less contrasting than the others.
Additional Knowledge - Explanation of Incorrect Options:
· Triad (Option B): A triadic colour scheme uses three colours that are evenly spaced around the colour wheel, such as red, blue, and yellow. This is a complementary scheme, not a related scheme.
· Tetrad (Option C): A tetradic colour scheme uses four colours arranged into two complementary pairs, such as blue and orange with yellow and purple. This is not a related colour scheme as it uses contrasting colours.
