Frequently asked questions about masking fluid
Coloured or colourless masking fluid?
There are advantages to both colourless masking fluid and tinted versions. Some artists prefer the colourless option as it is less visually distracting and makes it easier to imagine the final result while painting. Others prefer masking fluid that is lightly tinted or even bright blue, as it makes the rubber easier to see on the paper. It all comes down to personal preference and what best suits your subject or creative process.
