SpectraShop™ Graph 2D Examples

xy Gamut Graph

This is a common graph type available in many programs.

SpectraShop allows for gamuts to be displayed in any combination of two colorimetric variables.

The spectral locus can be optionally displayed when xy or u'v' graphs are selected.

Tonal Reproduction Curve

SpectraShop can create dot graphs, one variable plotted against the specimen names. This can be used for TRC curves or other relationships.

CIECAM02 Lightness vs CIECAM02 Chroma

Graphs can be created where groups of specimens are connected to show their relationships. In this graph one plane of the Munsell color solid is displayed with lines to indicate patches at the same lightness level.

This graph shows another unique feature of SpectraShop, although ∆E2000 is appearing in more programs, few also implement CIECAM02. Fewer still graph CIECAM02 values.

Printer Reproduction Accuracy Check

SpectraShop can display paired groups of values with direction arrows.

This is a great way to show the results of a color management system. The direction arrows can be used to visualize color changes such as the hue and chroma shifts visible in this graph.

The Graph Tool allows each group of specimens to be displayed with single color markers or each marker can receive it's specimen's color.

Munsell 6 Lightness Plane Connection Graph

Using the grouping and connection features of SpectraShop can produce some very useful graphs which are difficult, if not impossible, to create in other programs.

This graph shows the hue and chroma relationships of patches from the Munsell Book of Color.

Note that the sizes of the markers were reduced to better show the connection lines as the chroma lessens toward the center of the shape. This is easy in SpectraShop, hard in other programs.
