<em>FakeBRG</em>: This will not change the screen, but will swap around the RGB channels to become BGR. This will make all the colors gradients look mostly correct, and there won't be much difference on the whole screen, but images will look very different in applications that support color management.

To create a virtual profile for a digital camera just drag and drop one of the image files onto the <guiseq><gui>System Settings</gui> <gui>Color</gui></guiseq> dialog. You can then <link xref="color-assignprofiles">assign profiles</link> to it like any other device or even <link xref="color-calibrate-camera">calibrate</link> it.

Color profiles can be embedded into images to specify the gamut range of the data. This ensures that users see the same colors on different devices.

Every device that is processing color should have it's own ICC profile and when this is achieved the system is said to have an <em>end-to-end color-managed workflow</em>. With this kind of workflow you can be sure that colors are not being lost or modified.

The human visual system is not a simple RGB sensor, but we can approximate how the eye responds with a CIE 1931 chromaticity diagram that shows the human visual response as a horse-shoe shape. You can see that in human vision there are many more shades of green detected than blue or red. With a trichromatic color space like RGB we represent the colors on the computer using three values, which restricts up to encoding a <em>triangle</em> of colors.

Using models such as a CIE 1931 chromaticity diagram is a huge simplification of the human visual system, and real gamuts are expressed as 3D hulls, rather than 2D projections. A 2D projection of a 3D shape can sometimes be misleading, so if you want to see the 3D hull, install <code>gnome-color-manager</code> and then run <code>gcm-viewer</code>.

First, looking at sRGB, which is the smallest space and can encode the least number of colors. It is an approximation of a 10 year old CRT display, and so most modern monitors can display more colors than this. sRGB is a <em>least-common-denominator</em> standard and is used in a large number of applications (including the Internet).
