    Recenlty our production studio moved to a new location.
    To my horror as entering the new set up, all the wall were painted a
    very bright lime green after continous demands for it to printed 128
    grey to reduce color cast of the monitors. the lights are a bit
    yellowish too.( the glass) Oh well.

    Is there any good online explaination on what color will be cast into
    the monitor? actual green's to fix it and also
    why it does this... or if i'm just being plain ridiculous.

    Our studio has apple monitors of various age, calibrated weekly.

    Any advice appreciated.

    Someone saved money on the paint. Hard to say how bad it will be, but
    someone should be working the budget for a repaint over the weekend. The
    effect will be minimal if you work by the numbers, but if you rely on your
    eyes alone you will be even more vulnerable to systematic color casts in
    your final result.

    If the walls take up much of your field of view, a properly calibrated
    monitor will appear magenta, and this will tend to make your final images
    somewhat green. If this appears to be a serious problem, invest in a few
    rolls of art paper and cover the walls.

    If the walls are not that visible from your cubie, the lights will probably
    be more of a problem than the walls, and your final images will take on a
    yellowish cast.

    Cheap solution - turn out the lights and fix both problems at once.

    PS - cross posting this would have been good to save having two parallel

    Mike has some good ideas. One thing that I would do is use a 4-color meter,
    catch the lighting and the reflection from the wall and see just what color
    you are getting. The Minolta Digital 4-color has a filter conversion chart on
    the back that will tell you what the correction factor is.

    If you can, light your work area with a balanced light source, and do turn off
    the overheads.

    A short-term solution might be to build a 128 gray surround for your monitor
    with a hood to cut out the overhead sources.


    PS were it my studio, someone would be re-painting
