How are secondary colours obtained?

1. By mixing two primary colours

2. By diluting a primary colour

3. By adding black to a primary colour

4. By lightening a tertiary colour

The correct answer is: By mixing two primary colours

Secondary colours are colours that are formed by mixing two primary colours together. A is the correct answer because when two primary colours such as red and blue are combined, they create the secondary colour purple. B is incorrect because diluting a primary colour does not change the colour itself, but rather makes it lighter or less saturated. C is incorrect because adding black to a primary colour will result in a darker, muted version of that colour rather than creating a new secondary colour. D is incorrect because tertiary colours are already lighter versions of primary and secondary colours, so lightening them further will not create a new secondary colour. Therefore, the only way to obtain secondary colours is by mixing two primary colours together.
