Just to join in: My Exile usually wields a purple and a yellow/or red. I'm ALWAYS a sentinel. But I'll go red from time-to-time, but I keep the purple.
My male Exile will replace purple with Cyan - although the fact that a lightsaber with Cyan is ALWAYS active gets annoying.
Atton gets silver and/or orange (which is remarkably close to red, but also more manly than yellow).
Visas gets yellow, Brianna & Kriea get purple, Bao gets blue, Mira purple and/or yellow (again, for dual-wielding. I HATE dual wielding the same color light sabers). Mical will get green or veridian (or whatever that other lighter green color is)
When I go red, the whole bunch goes red, however. But I'll still mix 'em all up with silver, orange, and purple.
And I guess that about covers it. So yes, I guess I try to stick with class solors. But only when I feel like it, really, since everyone in the game seems to be a sentinel.
Also, I'd like to quote Wookieepedi under Light sabers:
"The color of a lightsaber blade was defined by the focusing crystal used in its construction. The Jedi collected crystals of varying types and hues from natural deposits, whereas the Sith made use of fabricated synth-crystals usually designed to emanate shades of red. After the purges of the Old Republic's Jedi order, synth-crystals were also shaped and used by Jedi on occasion. Luke Skywalker's green blade and Jaina Solo's violet blade both sprang from synth-crystals.
Prior to the final battle of Ruusan, ancient Jedi wielded blades of every color and hue. Some of the more common colors were orange, yellow, cyan, blue, green, viridian, violet, silver, and gold. Some ancient Jedi, such as Sylvar, even wielded blades of red hues, although the order typically avoided any colors that might associate them with the Sith. Red was also avoided since it was the most common representation of blood and violence. After the terrifying end of the Ruusan conflict, however, Jedi turned to more common Adegan crystals of blue or green coloration. Other colors, like bronze and brown, did still exist, but were extremely rare. Mace Windu, for example, braved the terrors of Hurikane to find his violet crystal.
In the era of the Jedi Civil War, the color of a Jedi's blade was a traditional symbol for the path the Jedi chose in his duties within the order, although a Jedi was not required to use a color that corresponded with his or her Jedi class. A green blade was the sign of the Jedi Consulars, scholarly diplomats and negotiators. Blue was the color associated with Jedi Guardians, the physically vigorous defenders of the galaxy. The third color, yellow, was held for those among the Jedi Sentinels, Jedi who found their skills balanced between physical prowess and scholarly awareness of the Force. For the purposes of the lightsaber's strength, these crystals functioned identically; color was the only variation.
After the Great Jedi Purge, Emperor Palpatine razed many of the known crystal sites, making it more difficult to find crystals of any hue. After the rise of the New Jedi Order, however, the discovery of long-forgotten resources and the use of synth-crystals brought a variety of colors back to the order's lightsabers. "
