The RGB and Lab triplettes can be defined by separating the numbers with space or comma.
However, this reduced precision has no practical impact on the use of the system. This is also why converting coordinates with Value less than 1 and above 9 or with Chroma below 2 is less precise compared to other regions of the color space. The Munsell space has been extended to the human eye gamut (thanks to the data provided by MCSL) through cubic interpolation of measured data and not by using simplified formulas. This can be done in RGB coordinates (2), assuming that the monitor is calibrated to White Point 6500K, CIE Lab (3), or in the Munsell notation (4) assuming an illuminant "C" (because the Munsell space is defined only for this illuminant). To obtain a paint recipe, first and foremost, it is necessary to define the target color (1). In the recipe transparent colors may appear as well, but the recipes are valid ONLY if there are also opaque bases to make the overall recipe opaque. Limitations: only opaque paints without fluorescent, metallic, glitter or other special effects can be mixed. Another reason for limiting the number of paint bases is simply when some of the bases parameterized in the system are not available to the painter. In this case, the use of various pigments in different areas of the painting creates unnatural effects with changing illumination (e.g.: daylight to artificial). This is particularly useful in cases when one tries to obtain the color of the reflection of an object. Furthermore, it is also possible to limit the number of paint bases to obtain the target color.
However, if the color error is below the threshold requested by the user, this system minimizes the drops or the parts of paint. This program, therefore, chooses the recipe that minimizes the color error (defined by the DE*94 formula). Various recipes can provide the same color experience thanks to the phenomenon called metamerism. The conversion from color coordinates to recipes is not unique like the conversion of paint recipes into color coordinates. The Munsell space defined in this system is based on cubic interpolation of the Munsell Renotation Data and not on a simplified mathematical model, thus bringing us very close to human perception. The RGB coordinates are not device independent, however, CIE Lab values or the Munsell notation (Hue Value/Chroma) may also be used to define the color. This paint recipe indicates the number of parts/drops of a paint base that needs to be mixed with other bases. For example, having an image on the computer, it is enough to read the RGB coordinates of a pixel and the program converts them into a paint mixing recipe. This program has been created to find paint mixing recipes corresponding to a target color defined by chromatic coordinates.
