That's the whole issue right there.
If you demand all depictions of Asians to look like some Californian Quarter-Asian model or closer to that than to the evident Asian people one could meet in -say- Asia, that's mostly a you-problem.
And the color-thing is even more ridiculous. It's simply hard to precisely hit the impression of color a human face gives in natural light with a reasonable palette. White people always end up looking way off, too. And they are all different from each other, too.
If all your Asian characters end up with any one uniform color or face structure, then you may have an issue with racism because you don't treat them as individuals.
But to try and dictate a single color for "Asian people"? Preposterous!
