What is the benefit of making a blending sample chart?

Correct answer: Different colour ratios and results can be compared

The governing concept is planned colour experimentation. A blending sample chart records which colours, proportions and moisture conditions were used, so the resulting shades and transitions can be compared before applying them to the final work. This helps the artist choose a reliable mixture and avoid waste. It cannot draw automatically, eliminate brush cleaning or change paper size. Therefore, option A is the practical benefit.
