The "restriction" seems pretty easy to achieve, as unless you have multiples no other card cares about being spent on colored mana costs. Similar mechanical meaning as "This mana can only be used to cast non-artifact spells."
oh yeah, spells is a little bit (though not much). It could also enter the battlefield tapped; 3 CMC artifacts adding mana are usually rather unimpressive, especially compared to Manalith and such like.
There are a lot of elements in the set file that are at odds with other components due to different phases of development. This was one of the earliest pieces of fixing that I put into the set, and part of the rationale behind it was that cheap colorless spells, regardless of the function, are beneficial to the Melody decks, even more so when they produce mana that allows bigger "chains". And restricting it from activating abilities/artifacts was to prevent the splashing of the powerful equipment with activated abilities.
Of course, after some testing with just the commons, I started expanding the amount of general fixing in the set, specifically the inclusion of Wedge-Obelisks, and the nature and quantity of activated abilities has been altered such that this probably doesn't need to exist.

The colour part isn't much of a restriction; but spells only is somewhat.
Probably ought to be cmc 3 though.

Changed it to a Power Armor variant.
(Previous comments refer to when it was "Gain 3 mana usable only on coloured spells)"
