Question

color picker and OCIO

In v7.4 with the initial OCIO implementation without support for OCIO roles the color picker works in the working color space (ACEScg for an ACES config). Hopefully this will change to use the color_picking role. It is problematic to us the AP1 gamut for picking colors for materials as this contains colors on the out gamut bounds only found in lasers. Better is to use scene-linear sRGB/Rec.709.

 

Secondly, the color picker currently samples the displayed color, including both lighting info as well as the Display Transform. A workaround in order to pick a color from the viewport is to change the Display color space  temporarily to Raw (thus removing the Display Transform) and also set the view to BaseColor  rather than Material mode (thus removing shading/lighting), to sample the color. It would be preferable if the color picker sampled the actual raw base color 1:1 from the view port. This is the behavior of many other DCC apps that use OCIO. Please consider this in a future release.

    Note that the second paragraph in my above post refers to the color picker with the help message "hold to pick color from screen." The Material Picker tool behaves as expected/desired.

    p.s. wish it were possible to edit posts here...

     

    It appears that the two eyedroppers have different functions. One picks material color, the other picks screen color. A relativley simple solution could therefore be to either:

     

    a) make them both have the same functionality (to pick the raw texture color as described above).

    b) make both available at all times. Currently the Material Picker tool is not available when a fill layer is selected for example.

     

    Thanks for listening 🙂

    Thank you for your feedback.

    We have several improvements related to the color picker that are coming up soon that should cover your requests. 🙂

     

    As for the roles, we have also a few things coming up on that but right now nothing is planned on controlling the color picker behavior from them. That's something we can look into however.
