" COLOR DEFINITIONS
" I link the Csound classes to some of the default highlighting categories
" defined in synload.vim:
   
hi link	csOpcode	Label
hi link	csOperator	Type
hi link	csHeader	Statement
hi link	csInstrument	Special
hi link	csVariable  	String
hi link	csdTags  	Special
hi link	csComment	Comment
hi link	csDefine	Define
hi link	csLabel 	Define
hi link	csString	String

" to change the appearance you can either:
" 1. link to some other default methods (i. e. Constant, Identifier, etc.) 
" 2. change the color definition of these defaults in synload.vim
" 3. instead of linking to defaults, define your colours right here.
"    For example, you can try the following lines:

" hi csOpcode   	term=bold	ctermfg=darkred 	guifg=red	gui=bold
" hi csInstrument	term=bold	ctermfg=lightblue	guifg=blue	gui=bold
" hi csComment  	term=bold	ctermfg=darkgreen	guifg=#259025	gui=bold
" hi csdTags    	term=bold	ctermbg=blue     	guifg=blue	gui=bold
"
" You can easily change them to suit your preferences.
