R'G'B' input in Adobe (1998) converted to the FED-STD-595B Color Deck (we can also convert FROM a Color Deck). We see that this is not an exact match, and the closest FED-STD chip is #14255, as represented by the square patch in the center of the L*C*h* pad, with a 2,26 CIEDE2000 error. The patches around the center one show the NEXT best matches in terms of closeness in saturation (+/- sat., i.e. chroma), luminosity (+/- lum., i.e. lightness), and hue; their IDs can be obtained by resting the mouse cursor over the patch until a popup tag appears (as shown above for the + sat. patch). Depending on the end use for the matched color, the match could be acceptable or not. To help make this decision, we can see if the difference is noticeable when we separate the two colors. When you click on the patches on the bottom of the display, you cycle through different patch layouts with various background colors and patch sizes. The layout shown below consists of two small patches separated by a gray background; the difference between the patches is much less perceptible, and this match could well be satisfactory for some uses where the matched color is not seen near or against the reference color.
