They do. It is xterm documentation that points out that XParseColor should be used, pointing out explicitly that colors may be specified by name or RGB specification. I have tried replacing Blue and Red with numbers and this is not working in xterm, neither it is in konsole. Rxvt-unicode indeed does something when it receives numbers in place of Blue and Red, but this is the only terminal that does this I have (also not the primary one (used to be once, changed to konsole due to a) 24-bit color support and b) much easier configuration if you need powerline fonts)), and this is going directly against original specification which specifies *only* XParseColor.

By the way, other color options supported by XParseColor are as well supported by konsole, xterm and urxvt. I have not tried all variants, but at least CIEXYZ:0.5/0.5/0.5 works.
