Tweak mode issue with hex codes including transparency.

Description

Love tweaks mode. Forgot how much I love it.

Anyway, I'm getting Syntax Error like Incomplete statement or extra code near ‘extraneous input 'A0' expecting ')'’? if there is a color with a transparent component included when running in tweaks mode.

Expected Behavior

Expected it to draw per usual. The same sketch will work correctly if run normally.

Current Behavior

The following will run normally but not in tweaks mode:

void setup() {
  size(250, 250);
}

void draw() {
  background(#FFFFFF);
  noStroke();
  fill(#C0A0A0A0);
  ellipse(50, 125, 200, 200);
  ellipse(200, 125, 200, 200);
}

Steps to Reproduce

Include a color with a transparent component like #C0A0A0A0
Run in tweaks mode.

Your Environment

This reproduces across operating systems.
