Message Codes

The Lab readout feature in Capture One Pro supports the most common and useful versions of profiles, however it will warn when a profile can be interpreted in more than one-way.

Lab readout message codes

While many different profiles are supported, a message will be displayed when a profile is either not compatible or can be interpreted in more than one-way. 

Error code

Description

Error 1

Unsupported profile: profile is not supported or invalid profile.

Error 2

Data Color Space not supported: only RGB profiles are supported.

Error 3

Profile Connection Space not supported: ICC specifies that the profile connection space can be either XYZ or Lab (the white-point must always be D50). While most LUT-based profiles use Lab, RGB profiles use XYZ. Currently, only XYZ-profiles are supported.

Error 4

Class not supported. Capture One only supports profiles with the classes; display, output and color space.

Error 5

LUT-based profiles not supported. Due to the large variance in the interpretation of LUT-based profiles, these are not supported for Lab readouts.

Error 6

Curves mismatch: profiles are rejected if the transfer function used for the RGB-channels do not match. Such profiles will not maintain a neutral color for R=G=B and are considered not to conform to the standard.

Error 7

Interpretation depends on intent: the profile can be interpreted differently depending on intent. Capture One will choose a colorimetric intent. Note that there is no distinction between relative and absolute colorimetric intents for Lab-coordinates expressed in the profile connection space (default).

Error 8

Transform is defined in two different ways: there is both a traditional and a v4 version of the transform and they do not agree. Capture One will base the Lab readout on the v4 specification.

Error 9 

Black cannot be represented: the darkest color that can be expressed in the color-space is not black. As a result, black point compensation may cause widely differing interpretations. See here for more information.
Error 10

Dark colors are slope limited: due to limitations in different color engines, dark colors may be interpreted differently. See here for more information.

Error 11

Adaptation white-point is unspecified or invalid (using media white): the profile contains an unacceptable adaptation method or the adaptation method was expected but missing. Adaptation is based on media white. See here for more information.

Error 12

Adaptation white-point is unspecified or invalid (using D50): the profile contains an unacceptable adaptation method, or the adaptation method was expected but missing. Adaptation will proceed to D50 or media-white is assumed to be D50. See here for more information.

Error 13

Media white is missing (using D50): the profile does not define media-white; D50 is assumed. See here for more information.

Error 14

Ambiguous PCS white-point: illuminant is not D50 as required by the specification. Different color engines will interpret the profile differently. See here for more information.

Error 15

Ambiguous PCS white-point: (255,255,255) is tinted. Different color engines will interpret the profile differently. See here for more information.
