Random Color
Yet another application I've developed (this time, in just one day): Random Color.
Note: I have developed Random Color a lot, and it has evolved into Prismatic. Go check it out.

I was writing the metainfo for Web Sharing and got to the brand color step. Not knowing a color, I thought about going through random colors, and realised that would be a good app. I finished it within a few hours.
There's still a few things before I'll call it "complete".
A few neat things about it:
- F10 is typically bound to the main menu by default when creating the UI, but since there isn't a menu here, I've manually rebinded it to open the About menu.
- Ctrl+R gets a new color.
- The UI widgets change color (white/black) if the default color won't meet Web Content Accessibility Guidelines (WCAG) contrast guidelines (3:1 for large text). Worse-case scenario, the tooltip text is the value as displayed (without the "Hex" or "RGB" prefix).
