Yellow is the complement colour of purple.
This answer comes from the colour wheel - a standard tool used by artists and designers which dates back to the 18th century.
The wheel is an arrangement of colours around a circle which shows the relationship between primary colours, secondary colours and complementary colours.
Primary colours are those which cannot be made by mixing other colours: Red, blue and yellow. These are evenly spaced around the wheel. Between these lie the secondary colours which are those which can be made by mixing two primary colours. Green is an example, as it is created by mixing blue and yellow. The complements then are the colours on the wheel that lie opposite each other.
Opposite purple on the wheel you will find yellow. When placed next to each other, complementary colours make each other appear brighter.
The use of complementary colours is an important part of creating things that are aesthetically pleasing so the wheel is an important tool in art and graphic design.
However, a word of warning, there is no straight-line relationship between colours mixed in pigment, which vary from medium to medium. So a painter's colour wheel is indicative, rather than predictive and is used to compare existing colours rather than calculate exact colours of mixtures. There are also going to be differences relating to the medium being used. Wheels can vary to a degree based on the paint or other medium that is being used. So many artists make their own individual colour wheels.
Putting 'colour wheel' in to Google and your search will come up with plenty of examples and all should put yellow opposite purple. There are also a number of interactive colour wheel applications available in which you can sample a colour and the software will generate the complement. These are useful if you are looking at the finest details of colours but otherwise, a quick glance at the wheel will do.
