Bullseye Rhubarb is the color I love to love and hate and crave. It may be my all-time favorite most annoying color.
Seriously...it goes with everything and nothing, just depends on the form factor of the glass (powder or billet), what glasses you're using with it, and how you light it. It may be one of the most powerful glass colors around, and can be tough to work with until you've experimented with it awhile.
Sheet-wise, remember that the color will change depending on the light in the room, so where you'll view it makes a big difference. If you're not sure, stick with neutral colors as companions.
This is a 9-inch pate de verre tile, where the background is pure powdered transparent Rhubarb Pink-Green to about 1/4 inch, then a mix of powdered Rhubarb against crystal clear fine frit as filler. It's displayed, variously, in summer sunlight, incandescent light (bronze), and fluorescent lights, so that background goes all the way from candy pink to bronze to lime green:
In Shout, though, I'm mixing Rhubarb billet with my second-favorite BE casting color, Burnt Scarlett Striker, and it completely changes character: It deepens the scarlet tones and really starts to glow a deep, fiery red:
That is, it glows red until you get it into fluorescent light. At that point, the whole sculpture does this bilious green thing that nearly made me rename it "Hangover."
In solid form (i.e., not mixed), the shift glasses give you a lot of additional dimensions, especially when you cast with them. They "shift" with changes in the wavelength of light, and so when the way the light strikes the glass changes, the color of the glass can change slightly, too. If you're making solid forms, especially with a lot of angles and thickness variations, you get a much, much richer, deeper color dimension.
The YouTube link is of a different glass manufacturer's Rhubarb (Gaffer)--it's a lead crystal goblet I made for a wedding. You can see the color changes it goes through in different lights, and how the shifts enhance the dimensions:

its not cheap.
