Color Picker Issues – Possible Explanations

After my post on the color picker issue last night I got an email from Dan at Microsoft with a possible explanation:

I have a couple of questions that might help narrow down the issue:
– Are you using the “Color eyedropper” on the color picker? This one picks the screen color. There is another “Color dropper” on the tool bar that picks the object color and is likely to give you better color fidelity in color correct environments.
– Are you using a system color profile? On Vista, under Control Panels, there is a control panel called Color Management. Could you check if you are using a custom profile other than sRGB?
The drawing surface of Expression Design uses the system color profile by default. Programs like Adobe Photoshop or Illustrator ignore the system color profile unless you specifically turn on proofing.
There is also another known bug with the Color eyedropper where it records colors by one digit (so 255, 0, 0 would be recorded as 254, 0, 0). This however, does not seem to be what you are seeing.

I was using the Color eyedropper when the error described in my earlier post occurred. But even if this dropper picks the screen colour it is still very inaccurate because the colour picked doesn’t match the screen colour either.

I am using a system color profile generated by Pantone’s Huey device.

I am not at my regular computer at the moment but I will check all of the above later on today to get to the bottom of this. Stay tuned …
