Frequently asked questions
How do I choose duotone colours?
Pick one dark and one light colour that contrast well, such as deep purple and pink. Similar brightness makes the image flat and hard to read.
Which colour pairs work well?
A dark colour with a bright, contrasting one usually looks bold, such as deep purple with pink. Avoid two colours of similar brightness, which flatten the picture.
What kind of photo suits duotone?
Pictures with strong light and dark areas and a clear subject work best. Busy, low-contrast photos can lose their shape in two colours.
