Transform

Select an option from the Rendering Intent drop-down menu (rendering Intent refers to the conversion of one color to another).

Perceptual (default). Compresses the total gamut from one device’s color space into the gamut of another device’s color space when one or more colors in the original image are out of the range of the destination color space. This preserves the visual relationship between colors by shrinking the entire color space and shifting all colors, including those that were in the gamut.

Relative Colorimetric. When a color in the current color space is out of gamut in the target color space, it is mapped to the closest possible color within the gamut of the target color space, while colors that are in gamut are not affected. Only the colors that fall outside of the destination gamut are changed. This Rendering Intent can cause two colors, which appear different in the source color space, to be the same in the target color space. This is called “clipping”. Relative colorimetric is the default method of color conversion built into Photoshop.

Absolute Colorimetric. Colors match exactly with no adjustment made for a white point or black point that would alter the image’s brightness. Absolute Colorimetric is valuable for rendering “signature colors”, those colors that are highly identified with a commercial product such as the yellow used by the Eastman Kodak Company™ or the red used by the Coca-Cola Company™.

Saturation. Reproduces the original image color saturation (vividness) when converting into the target device’s color space. In this approach, the relative saturation of colors is maintained from gamut to gamut. This rendering intent is primarily designed for business graphics, where the exact relationship between colors (such as in a photographic image) is not as important as are bright saturated colors.

Color Wheels Layout

Capture One’s color wheels used in the Color Balance and Color Editor tools located in the Color tool tab can be displayed with the chroma hue reference phase rotated 90-degrees to imitate a Vectorscope layout. Select the layout as appropriate. Capture One does not require restarting.
