The standard LCARS colors from Voyager are ORANGE: #FF9900, MANGO: #FF9966, LILAC: #CC99CC, PURPLE: #CC6699, BRICK: #CC6666, NAPLES: #FFCC99, PALEBLUE: #9999CC, and SKYBLUE: #9999FF.
Also, GRAY is #99999, and there is also a deeper blue, seen on Nemesis and on the Defiant, which I call in my source code BIGBLUE: #6666FF. There are numerous sources that will at least confirm the first eight above.
Your fonts look better than most. TrueType is good for general fonts, but LCARS fonts in the smaller sizes require custom drivers. Anyway, I prefer to make 13-point the minimum size for LCARS fonts.
Here's the thread about my working LCARS system. There is no Windows version. I may experiment with one when I have time. Anyone who wants this can download it free, but it requires a TrueColor laptop of its own, one with a standard graphics card and sound card, which most of those made after 1998 don't have. The program has embedded drivers for a few of the oddball cards, not many, and it only runs under DOS, not Windows.
