A student is carrying out a colour‑mixing experiment using the primary paints red, blue and yellow. The aim is to produce a secondary colour, then a tertiary colour, and finally to identify its complementary colour on a standard colour wheel. The student records the volumes of paint used as described in the tasks below.

Question Parts

( a )
The student mixes 40 ml of red paint with 30 ml of yellow paint to obtain orange. State the ratio of red to yellow used, expressed in the simplest whole‑number form.
( b )
To obtain a tertiary colour called "red‑orange", the student adds 20 ml of the orange mixture from part (a) to 10 ml of pure red paint. Calculate the percentage (to one decimal place) of red paint in the final mixture.
( c )
Using a standard 12‑segment colour wheel, identify the complementary colour of the tertiary colour "red‑orange" produced in part (b) and briefly explain why it is complementary.
( d )
Discuss two possible sources of error that could affect the accuracy of the colour‑mixing results and suggest one method to minimise each error.
