wheel of fate is red? why does it has to say so?

[kevin]

pulled a card called wheel of fate from time spiral, why does it say "wheel of fate" is red? I can see its red without saying? like on my Nantuko Shade it doesnt say that nantuko shade is black because it doesnt need to?

[riolu]

its because time spiral is a set with cards reprinted from older sets

under the new rules a card's color is the color(s) that in its mana symbols in the mana cost so like if a card costs 2R to cast it will be red, and if a card costs RG to cast it will be green and red

Expanding on Riolu's answer - as he said, a card's colour is determined by its mana cost. However, Wheel of Fate doesn't have a mana cost. Without the "Wheel of Fate is red" text, it wouldn't be a red card.

wheel of fate is not a reprint of any card as far as I know... and the rule youre mentioning about a cards color is not "new" its always been like that
