Yellow.
What are complementary colours?
Colours directly opposite of each other on the colour wheel.
Give an example of complementary colours.
Blue & orange.
What are analogous colours?
Colours that are adjacent to each other on the colour wheel.
Give an example of analogous colours.
Blue & blue-violet.
What effect do complementary colours have?
They create dissonance and are used to make an object stand out.
What effect do analogous colours have?
They appear less stark and show moderate distinction.
What can overuse of complementary and analogous colours lead to?
Increased cognitive load and potential distraction for the audience.
What are categorical colour schemes?
Colour schemes for discrete groups (isolated).
What is a key characteristic of categorical colour schemes?
Use a distinct colour for each group.
What are sequential colour schemes?
Schemes where the value of the variable can be arranged in ascending or descending order. Single hue (saturation or luminance is increased or decreased) to create a gradient.
How are sequential colour schemes created?
Using a single hue and varying saturation or luminance to create a gradient.
What are diverging colour schemes?
Schemes that use two sequential colour schemes, one for below and one for above a meaningful reference value.
What are the common mistakes in data visualisation regarding colour?
Unnecessary colour. Excessive colour. Insufficient contrast. Inconsistency. Neglecting colourblindness. Not considering mode of delivery.
Name the common mistakes in using colour in data visualisation.
Unnecessary colour, Excessive colour, insufficient contrast, inconsistency across visualisations, neglecting colourblindness, not considering mode of delivery
What is one issue related to contrast in data visualisation?
Insufficient contrast.
What is a mistake related to consistency in colour use?
Inconsistency across related charts.
What should be considered regarding colour blindness?
