How do you see color? Good color perception is of ultimate importance for matching color in dental restorations. We have provided an online color-vision test, based on the Ishihara color vision testing system. The test will evaluate whether you have a red/green color deficiency, or any color blindness which affects your ability to correctly match color for tooth restorations. Full spectrum lighting is a critical factor in matching color. The ambient light volume in dental operatories is almost always insufficient for correct color evaluation. We offer a solution in our full spectrum zone light for your operatory.
