I am a long time Vim user, but I downloaded MacVim for the first time this last weekend. One of the first things I noticed is that my color scheme in a syntax highlighted file did not look right.
The information in :h macvim says this about Colors.plist "Apart from the system colors, it is also possible to use standard X11 color names (see http://en.wikipedia.org/wiki/X11_color_names) which usually come in a file called "rgb.txt". MacVim does not have such a file, instead it keeps these colors in a dictionary called "Colors.plist". The key in this dictionary is the name of the color and the value is an RGB value of the form #rrggbb stored as an integer." First, those colors are easily accessible on every Mac with X11 installed. Simply run "showrgb" program (/usr/X11/bin/showrgb). The numbers seem to correspond to the Wikipedia article. However, it turns out those integers in Colors.plist are not right. Take, for example, the value for MediumAquamarine: 6737066. Now take a look at the Wikipedia page. The RGB numbers are 102 205 170, or #66CDAA The showrgb program gives the same decimal numbers for this color. Let's open a terminal and check the hex number in bc. $ bc ... obase=16 102 66 205 CD 170 AA ^D So Wikipedia hex value is correct. Let's now use bc to convert this hex value to an integer. $ bc ... ibase=16 66CDAA 6737322 ^D Ouch. 6737322 != 6737066 (value from Colors.plist) Similarly for practically all other colors! I don't know how these numbers have been obtained, but they are simply wrong. Even a simple color, such as Blue, is wrong -- 212. It is clear from that Wikipedia page that Blue is #FF (0 0 255). I mean, it's the B in RGB. :-) Now, being someone who prefers programming to typing huge amount of numbers I have written the attached program to generate the *correct* Colors.plist using the output of "showrgb" X11 utility. I hope it gets used in the next MacVim snapshot. Attached is also the correct Colors.plist generated by that program. You can run the program on your Mac and compare that it produces the same plist.
