  • Changing mutilple Solid Layers Color Via Expression/Slider

    Posted by Andy Joseph on October 2, 2013 at 7:59 am

    Hi Guys,

    I’m using a single solid layer in 10 different comps using it as overlay color effects. I can easily apply the same color to all the layers at once by selecting “Affect all layers that use this solid” while changing color via solid settings.

    Now i’m looking for a solution where i can use color sliders expressions to do this. Or may be by applying the some color effect to all the layers & change them through a common slider in main comp.

    Thanks
    Andy

    Here’s two ways to do it:

    Make all your solids bright green, or some obvious color. On all of these green solids add a “Change to Color” effect. Make the “From” color the bright green.

    Then on a null in your main comp, add the effect “Color Control”. Link the Change-to-Color’s “To” color to that Color Control in the main comp.

    When you change the Color Control in the main comp, all of the solids will change to that color. Note that it is sometimes not an exact change to the specific RGB values, but it’s pretty close, and you can fiddle to get it right.

    The other way to do it is to use big full-screen shapes instead of solids. You can directly link the shape’s “fill” to the color control (don’t have to mess with Change-to-Color”), so you can be completely accurate on the RBG values when they propagate to all of the shapes.

    Cheers.

    Thanks Mitch,
    The second approach sounds good to me. I’ll try & let you know.
