It is because turmeric is an acid and soap is a base . And we know that when base is rubbed with acid it turns its colour red.

Explanation:
Turmeric is an indicator and soap is a base
The turmeric indicator changes colour between roughly a pH of 7.4 and 8.6. If turmeric is exposed to neutral or acidic substances (those with a pH of less than 7.4) it will retain its yellow colouration.
