Lines: 52 Keywords: Preferences Somebody here asked what screen colors work well in interlace mode. I cant find the original article, but... The flicker you see in interlace (400 line) mode is caused by a sharp difference in contrast between two colors. Black and white are about the worst. To minimalize flicker, you want to minimalize contrast. Now if you make the screen use two colors that are the same, no flicker, but, uh, you cant see it. So, you try to keep lightness and saturation constant, and only change hue. Since Preferences works with RGB not HLS, this is somewhat less than intuitive. What I did was to set my workbench to interlace and run preferences, and then spend about two weeks playing with it, seeeing what works, what doesn't. Anybody who has seen Draw Plus has noiticed that although the screen looks kind of dark, it doesn't flicker a whole lot. Thats because the lightness and saturation of the blue and grey used are pretty close, the only diference being hue. I find dark gray and black (well, not quite black, more like rgb = 2,2,4) works quite well. Also, if thats too dark for you, a light blue (~ 4,7,10) and beige (~ 9,7,5) seem to work pretty well. Its funny. When I first got my amiga I looked at the stock blue and white screen, and thought "Hmm, that has to go". I have changed it over the last 18 mos. to almost every possible color combination (red text, yellow text etc.) and what do I use now ? The original blue for background and light peach for text. Full circle. (almost) -- Richard Sexton INTERNET: richard@gryphon.CTS.COM UUCP: {akgua, hplabs!hp-sdd, sdcsvax, ihnp4, nosc}!crash!gryphon!richard "It's too dark to put the key in my ignition..."
