 ### `util.lerp(t, v0, v1)`
 Straightforward linear interpolation of two numbers: `(v1 * t) + (v0 * (1 - t))`.
 
-### `util.gbc(c1, c2, interp)`
+### `util.gbc(c1, c2, interp, t=util.cx())`
 A somewhat flexible function for gradient-by-character effects.
 Typical usage would go in a `mixin char` component and look something like `{\3c!util.gbc('&H0000FF&', '&HFF0000&')!}`.
 If no `interp` function is provided, I will try to guess how to interpolate the two values.
@@ -357,6 +357,9 @@ At the moment, this means:
 
 If this is unsatisfactory, well, that's why I expose this function's third argument: specify your own interpolation function with a signature analagous to `util.lerp`'s.
 
+### `util.multi_gbc(cs, interp, t=util.cx())`
+Like `util.gbc`, but accepts a *list* of colors, for multi-stop gradients. Nifty.
+
 ### `util.rand.sign()`
 Either -1 or 1, randomly.
