I recently darkened my terminal's background (easier on the eyes!), but now, when I put multiple terminals on top of one another, they kind of meld together.

Previously, the shadow was what made it easy to differentiate them. How can I, say, make the shadow a nice crimson (because I'm edgy) and darken it so it'll be visible when terminals are laid over one another?

You should modify the unity.css file of the theme. Here is an example from a theme I modified.

UnityDecoration {
    -UnityDecoration-extents: 28px 0 0 0;
    -UnityDecoration-input-extents: 10px;

    -UnityDecoration-shadow-offset-x: 0px;
    -UnityDecoration-shadow-offset-y: 3px;
    -UnityDecoration-active-shadow-color: rgba(0, 0, 0, 0.3);
    -UnityDecoration-active-shadow-radius: 10px;
    -UnityDecoration-inactive-shadow-color: rgba(0, 0, 0, 0.1);
    -UnityDecoration-inactive-shadow-radius: 5px;

    -UnityDecoration-glow-size: 10px;
    -UnityDecoration-glow-color: rgb(221, 72, 20);

    -UnityDecoration-title-indent: 10px;
    -UnityDecoration-title-fade: 35px;
    -UnityDecoration-title-alignment: 0.0;

There you see the shaddow properties which are pretty human readable, at least developer readable. Everybody should know CSS. :-)
