Color Evaluator Glasses - Red & Green Lenses - Cover or Close One Eye to See Your Projects Color Value (Gray Scale) and Get the Right Contrasts - 1 Pack

Viewing your project through the Color Evaluator lenses is like seeing your project in grayscale or a black and white photo. You only see the value of the color (light, medium, or dark) and not the actual color. Seeing the values helps you select the materials in your project for the desired contrast. Wear the glasses to view your project. Close or cover your left eye to use the Red lens on projects that don’t have reds. Close or cover your right eye to use the Green lens on projects that don’t have greens. Alternate which eye is closed/covered to better understand the differences. Dark colors seen through a lenses will stand out the most, while light colors will fade into the background.
