Hello, I didn't find a thread for UTAU theming, so I decided to make one. For those of you unfamiliar with the process, you basically edit a bunch of color properties in the setting.ini file in order to change the look of your UTAU user interface. A good reason to do this is that if you use your computer in the dark a lot (I do), the default white background can be hard on the eyes. As such, i changed it to a dark gray background. Here's my theme: Code: COLOR_PIANO1=&H8E8888 COLOR_PIANO2=&H3A3A3A COLOR_ROLL1=&H423A3A COLOR_ROLL2=&H474444 COLOR_SEPA1=&H10CEFD COLOR_SEPA2=&HFF8080 COLOR_BACK=&H8E8888 COLOR_FORE=&HA4A4A4 COLOR_SHADOW=&H808080 COLOR_NOTE_NOR=&HFFC000 COLOR_NOTE_TOP=&H40DC3C COLOR_NOTE_SEL=&H40DC3C COLOR_NOTE_TNOR=&H857E7E COLOR_NOTE_TTOP=&H837C7C COLOR_NOTE_TSEL=&H837C7C COLOR_NOTE_RNOR=&HFFFFFF COLOR_NOTE_RTOP=&HC0C0C0 COLOR_NOTE_RSEL=&H808080 COLOR_PTCH_SEL=&H0000FF COLOR_PTCH_NOR=&HFF0000 COLOR_TEMPO_NOR=&H000000 COLOR_TEMPO_ALL=&HFF0000 COLOR_PITCH_NOR=&H808080 COLOR_SELECTBAR=&HC0C0C0 COLOR_HILIGHT=&H00FFFF Also, a good way to change themes is to first copy and paste the original setting.ini file, so you have a backup of the original. Then, you can open up the file in a text editor (notepad, etc) and then paste in the theme code. If you don't like the theme, or want to go back to the default for any reason, just delete setting.ini and rename the copied file (usually setting - copy.ini) to setting.ini, and you'll be good to go.
