Convert from a Munsell chip to a RGB Space

The screenshot above shows the Munsell 7,5BG 4/8 color chip (from the Munsell Color Deck) being converted to sRGB. To navigate within the Munsell Color Deck, we have used the List mode, where the color patches are presented in the order they are stored in the database. We could have also used the other deck navigating mode, the L*C*h* pad, shown in the next screenshot. We see that the selected chip, located in the middle of the list on the LEFT side, and represented by the green square in the chromaticity diagram, is NOT within the sRGB gamut, and the red sRGB coordinate is clipped to zero ( ! ). You will notice that the patch display, the two squares below the chromaticity diagram, has no clipping indicator; this is due to the selected display profile corresponding to a large gamut display (NEC PA241W) which covers the Adobe (1998) space almost completely. The currently selected display profile can be seen in the help tag that appears when the mouse is stopped over the patches. If we change Space #2 to Adobe (1998), we obtain the screenshot below.
There is no clipping when converting this Munsell color to Adobe (1998); this can be confirmed by the absence of clip indicators over the RGB data values of Space #2, and by a color-difference of zero. We also see that the Munsell HVC coordinates in Space #2 are the same as the Color Deck patch. Note: In BabelColor CT&A, you can use over 4000 Munsell color chips as input. You can also convert TO Munsell with fractional accuracy (with one decimal in H, V, and C) by selecting the "HVC Munsell" space in the menu located below the RGB label, as we can see just above on the right, and in this other screenshot. |
