So, should iKON use orange as their official color or not?

To be brutally honest, I hate it when other groups use PINK as their fandom color. Because I think it is the identity of both SNSD and Sones. Eventhough, up till now, the pink ocean still belongs to my queens SNSD, I still feel like it is their color and I don't want anybody use it as theirs. But, since SNSD never really minds it, or makes a fuss about their official color or everything, I become more and more tolerate about this kinda thing actually. Like, PINK is not for SNSD to keep, so everyone can use it. Although deep in side, still, I think it belongs to my queens.

Such as this:

But this one is just too harsh. I know Shinhwa is a huge sunbae group whom hoobaes must respect. I don't know why but I think Shinhwa made such a big deal of this thing. iKON won't steal their thunder anyway. And causing a fanwar and admitting that ORANGE is theirs, it just annoys me a lot ya know. COLORS ARE NOT MADE TO BE OWNED OMG. Everybody has rights to use any color as much as they want. Like, EXO, B2ST and BTS, they have the same fandom colors and nobody really makes fuss about it. Even the members of those groups don't care about it since they know their fans will always be there for them even if the colors are not used as their identities tho.

But, I don't know. This is just my opinion.
What do you think guys? Should iKON use ORANGE as their official color or not?
