Nifty Viscolor creates Winamp's viscolor.txt. NV can create the colors for either the spectrum analyzer or oscilloscope (the thingy that looks like a ocean wave). With NV you can choose from preset color schemes or use your own custom schemes. The finished spectrum analyzer or oscilloscope colors will smoothly blend into each other.
Viscolor.txt contains the various colors that appear in the visualization area of Winamp. Viscolor.txt consists of 24 rows of comma-delimited color data in the r, g, b format (i.e. 255, 0, 255 represents a bright purple).
Below is a sample viscolor.txt (taken from Winamp's base skin), followed by a brief explanation of what each row represents.
0,0,0, // color 0 = black 24,33,41, // color 1 = grey for dots 239,49,16, // color 2 = top of spec 206,41,16, // 3 214,90,0, // 4 214,102,0, // 5 214,115,0, // 6 198,123,8, // 7 222,165,24, // 8 214,181,33, // 9 189,222,41, // 10 148,222,33, // 11 41,206,16, // 12 50,190,16, // 13 57,181,16, // 14 49,156,8, // 15 41,148,0, // 16 24,132,8, // 17 = bottom of spec 255,255,255, // 18 = osc 1 214,214,222, // 19 = osc 2 (slightly dimmer) 181,189,189, // 20 = osc 3 160,170,175, // 21 = osc 4 148,156,165, // 22 = osc 5 150,150,150, // 23 = analyzer peak dots
