heres some handy dye charts, which include links for advanced dye tecniques (more than 1+1 dye mixes) and a handy chart for double dye mixes we have from our own guys here
http://www.guildwarsguru.com/forum/s...ad.php?t=25784
many people have difering views on whether its standard silver+yellow for gold, or a more advanced way, with up to 4 dyes in total.
the basic 1+1 chart shows lots of basic shades, and the link to the fuller Advanced chart shows many more mixes.
theres also a handy color wheel showing dye jobs for Monks tatoos and Necro scar patterns (which are different than cloth) and a chart to show how to dye your chaos axe (which also reacts differently )
hope this is usefull
