The Ultimate Collector's Series, or UCS, is a LEGO subtheme of Star Wars introduced in 2000 and was meant to be more detailed and aimed at older builders. These Ultimate Collector's Series sets tend to be larger, and more expensive than typical sets.
2004 LEGO Sets
In 2004, LEGO underwent a major shakeup as it worked to recover from record losses in 2003. This year saw significant changes in product strategy, color design, and partnerships, all of which played a role in LEGO’s long-term turnaround. One of the most controversial changes was the replacement of several long-standing LEGO colors, including gray, dark gray, brown, and violet, with newer, more vibrant shades. This shift also included the introduction of light nougat, which became the standard skin tone for many licensed minifigures.
