When color management is enabled and you move the Eyedropper tool over the image displayed in Viewport 2.0 or the Texture Baking View, the displayed numbers reflect the color values of the rendering color space, that is, the raw color values before the view transform has been applied. On the other hand, the color swatch displays the resulting color in screen space after the view transform has been applied.
The exception is when the view transform contains a 3D LUT, which is the case for ACES RRT as well as many transforms that may be used as user transforms or in OCIO configurations. In these cases, the display color values are selected with no transform applied.
You can toggle Attribute Editor. This setting is stored in your user preferences. Solid colors and ramps use the View Transform set in the Color Management preferences — temporarily changing the view transform on the viewport or Render View toolbar has no effect on color pots in the Attribute Editor.
to toggle the view transform on and off for solid colors and ramps in theThe color chooser and color picker always use the view transform, even if Color Managed Pots has been turned off in the Attribute Editor.
The sample swatches shown above shader attributes in the Attribute Editor are currently not color-managed.
