The computer color matching instrument (or computer color matching system) equipped with a full set of paint color matching software, database establishment and analysis software has a very good color paint formula function. When in use, as long as the pigments used for color matching are made into coating films of different color densities, input into the computer through the Spectrophotometer and stored, and then input the standard color to be prepared into the computer, then several pigments can be selected artificially, so that The computer makes the color paint composition formula that meets the standard color . Usually, the formulas provided by the computer are arranged in two sequences, one is arranged according to the size of the color difference, and the other is arranged according to the cost. In this way, it is possible to select a formulation that is satisfactory both in terms of quality and economy for the pigmented paint product.

If you use a computer color matching instrument (also known as a computer color matching system), because this instrument has no color matching function, it can only display the chromaticity data of the color, (L*a*b* value or L*C*H° value and ΔE, etc.), then it is necessary to look at the color difference ΔE and the color deviation direction judged by ΔL*, Δa*, Δb* (such as reddish or green or blue or yellow), depending on the operation According to the experience of color matching, make adjustments, and then use the instrument to test, after several cycles, you can also match a satisfactory color. Practice has proved that it is much faster and more accurate than relying solely on manual visual colorimetry.
It is undeniable that the human eye's ability to distinguish colors is often better than that of instruments. However, the rapid color matching of the instrument and the formula that can provide multiple pigment combinations for the same color paint cannot be achieved by manual daily color testing. Combining the professionalism of the instrument and human experience can achieve a perfect state.
We should not favor the sharpness of normal eyes and ignore the professionalism of the computer color matching instrument, but we should also keep in mind that no one will like the color it represents based on the data displayed by the computer.
