Yeah. About the only way to get anything other than an increased number of LOCAL colors (i.e. /echo) is to get all IRC clients (or at least the main ones) to agree on adding the support at about the same time and to add the same colors as default. Even then, if you add more than 0-99, it will always fail on anyone using older clients (the next number would be visible in them). Even so, 100 colors should be plenty for most people and as long as the main clients all agree on a "standard" and update about the same time, it shouldn't break anything. I think most clients automatically change colors > 15 to a 0-15 color... even if it's just the default color.
