You only have to meet threshold of cards, it does not factor into the actual 'cost' aspect. In HEX, if you had the similar of two Ruby shards, and two Blood shards, and had a resource count of four, you would be able to play both of those cards. If you had two cards costing RR and RB in Magic but only had two Mountains and two Swamps, you'd only be able to cast one of those cards.

In HEX, you're limited by threshold and separately, resource count. In Magic, you're limited by the number of coloured lands you have in play to cast spells. It's similar but fundamentally different. To be frank, HEX differentiated itself from Magic right from the onset.
