When ls/dir colorization is active, the following is used for directories: DIR 01;34 # directory This means that directories in /bin/ls output will appear in bold blue over whatever background color is set in the terminal. Quite often that background color happens to be black (such as in VGA text consoles) or another dark color. The way the human eye works and the way screens and monitors are made to match it, blue only accounts for 11% of brightness of white (while it's 59% for green and 30% for red). See, e.g., http://www3.ncsu.edu/ECE480/480_tvc.htm for details. This means that typical human beings (not just me) will have trouble reading blue on black. (All this to say that this is not a simple matter of taste.) The implication of this is that if blue is to be chosen as a foreground color, then a complementary background color has to be specified too. White and yellow are good choices. Therefore, I suggest the following line for DIR_COLORS: DIR 01;34;47 # directory This would keep blue as a foreground color and cause the least surprise to everybody that is used to it. Those already using a white background will not even see the change. Those using a dark background will no longer have to damage their eyes to read it. Note that the same problem occurs for yellow on white and that yellow on black is already forced for FIFO, BLK, and CHR files in src/dircolors.hin and src/dircolors.h (but strangely not in src/ls.c). Making the proposed change would bring more uniformity among default color choices. A patch for the relevant files follows. Note that I didn't correct the src/ls.c inconsistencies for pi:, bd:, cd:, and or: entries in color_indicator[] (as compared to src/dircolors.*).
