That's not quite it. The Hollow "White" merged with the Zanpakuto Spirit and became "Zangetsu", but its true form is still "White".

Besides, the Hollow's name is not the Resurreccion, it's power or source is. For example, Grimmjow's Resurreccion is called Pantera, not Grimmjow. The reason Grimmjow's Resurreccion is called Pantera is because of its Panther related power.

Ichigo's White Form is sourced from the original White, so its more appropriate to called it Los Blanco or Blanco than it is to call it Zangetsu. Because the Hollowfication draws nothing from the actual Shinigami powers Ichigo's Zangetsu is a part of, its all White.

It is specifically stated that the "White" Hollow transferred from Masaki to Ichigo upon Ichigo's birth, that is really White inside of Ichigo that fused to his Shinigami Powers/Zanpakuto Spirit.

When Ichigo's Hollowfied during his training with Urahara though Zangetsu's hollow powers attached to the Hollowfication, allowing Zangetsu to seize control of Ichigo through the Hollowfication.

Now, if we are talking about his Zanpakuto or Merged Hollow form than you might have a point, because that is Ichigo drawing from his Zanpakuto and mixed origin rather than the Hollowfication that he was using previously. You have to remember his Hollowfication and his Zanpakuto's abilities are two different things.

However, even that Hollow form was not White. White specifically showed up during the battle with Ulquiorra, both out of a need for greater power and because Ichigo had been absorbing reiatsu from Hueco Mundo, which Chad confirmed makes Hollow-based abilities stronger.
