تعریف و معنای "drawdown card"

What is a "drawdown card"?

A drawdown card is a tool used in painting to test and compare paint colors and finishes. It is typically a card with a section where paint can be applied and spread out to see how it looks when dry. The card often has areas marked in black and white to help evaluate how the paint's color and finish appear against different backgrounds. The black and white areas provide a contrast that makes it easier to see the true color and texture of the paint, helping artists and designers in choosing the right color and finish for their projects.
