Color management
Last updated 9/30/2011
Absolute Colorimetric Leaves colors that fall inside the destination gamut unchanged. Out-of-gamut colors are
clipped. No scaling of colors to destination white point is performed. This intent aims to maintain color accuracy at
the expense of preserving relationships between colors and is suitable for proofing to simulate the output of a
particular device. This intent is particularly useful for previewing how paper color affects printed colors.
Advanced controls in Photoshop
In Photoshop you display advanced controls for managing color by choosing Edit > Color Settings and selecting More
Options.
Desaturate Monitor Colors By Determines whether to desaturate colors by the specified amount when displayed on
the monitor. When selected, this option can aid in visualizing the full range of color spaces with gamuts larger than
that of the monitor. However, this causes a mismatch between the monitor display and the output. When the option
is deselected, distinct colors in the image may display as a single color.
Blend RGB Colors Using Gamma Controls how RGB colors blend together to produce composite data (for example,
when you blend or paint layers using Normal mode). When the option is selected, RGB colors are blended in the color
space corresponding to the specified gamma. A gamma of 1.00 is considered “colorimetrically correct” and should
result in the fewest edge artifacts. When the option is deselected, RGB colors are blended directly in the document’s
color space.
Note: When you select Blend RGB Colors Using Gamma, layered documents will look different when displayed in other
applications than they do in Photoshop.
