Good question...this is depend on individual with what he / she prefer colour, that the reason you better DIY using those tool, also it is free hence the consultant only give advised base on what your prefer else he/ she will choice from you.
Example: I ask my Kids what the prefer, than I informed the consultant, the he do the matching including the code, but at that end I select more light colour from the list.

ALternative your could got for ID too, which will be charging you each design.
From how you respond, I guess you already have idea what your preference rights?
