whats the grey/green thing mean...Follow

when u look at the blacksmith recipe table on this site?

its the recipe level in relation to your tradeskill level. This is imporant to know when looking for skill up to improve with.

So the list is as follows:
Red: cant learn yet.
Orange: just learned pretty tough always get a skill up.
Yellow: Equal or very close to your level. mostly get a skill up
Green: easy for you. occasionally get a skill up.
Grey: you could do it in your sleep and do. no skill up.

same scale applies to mobs incidently.. Why the site lists only grey/green im at a loss to answer.
