Final answer:
A synonym for a stain that leaked through is "seeped," which indicates a substance penetrating another material, often causing discoloration or damage. This concept is illustrated in art through Soak-Stain painting, where paint is diluted and poured onto canvas, allowing it to seep through.
Step-by-step explanation:
A synonym for a stain that leaked through might be "seeped." This term conveys the action of a substance passing through a material, often in a way that causes damage or discoloration.
For instance, in the sentence, 'Then she said that the paper stained everything it touched, that she had found yellow smooches on all my clothes and John's, and she wished we would be more careful!', the word smooches could be replaced with seeped stains to describe the marks left by the leaking substance.
The technique of Soak-Stain painting, as pioneered by Helen Frankenthaler, also involves the concept of stains leaking through. The process where the artist dilutes paint and pours it onto raw canvas, enabling the color to seep into the fabric, is an artistic application of a stain that penetrates a material.
