To see or use a colouring book in a dream represents childhood. Perhaps you have a carefree attitude and relish in the fast you have no responsibilities- just like a child. On the other hand, maybe you need to be more childlike in your waking hours if you have been quite serious about everything lately. You may just need to have some fun.
The dream could be warning to you not to waste your time on fruitless pursuits and invest it in more meaningful tasks or relationships.
Consider what you were colouring in- whatever was depicted in the colouring book might just be what you need to focus your creative energies on.
If you were colouring within the lines, then you may boast an adequate amount of self-control in your waking hours. On the flipside, you may be controlling every element of your life to the extreme and its preventing you from actually living it.
If you were colouring outside of the lines then you may benefit from some self-restraint. Perhaps you are crossing a line and its causing you or others problems either in your personal or professional life.
Another thought is that a colouring book represents a goal that you are emotionally invested in. You are trying carefully to make sure that the end result is perfect. Think about how much of the picture you had completed- this could be an indication of how far you are away from reaching this goal.
The act of colouring in a picture could be your subconscious telling you to explore your hidden creative talents more. This could be literal- you may have potential in something like painting, drawing or illustrating. Or it could refer to another creative aspect of yourself you have yet to unleash.
Or perhaps it was telling you to look on the bright side of life rather than focusing on the negative things that happen to you.
