Your current skill
The colors on the item list determine your skill level in regards to that item in the Dragon Ball. For instance an item that is orange would mean that it is very close to your current skill and will give you a skill point on creation. Yellow means it is close to your current skill and will most than likely give you a skill point. Green means that it is far away from your current skill level and might not give you a skill point on creation but the chance is there. Gray means the skill is far from your current skill level and will not give you any skill points no matter how many times you create that item. dragon ball gold would be something above your current skill level, although you can not learn any patterns that are above your skill level.
