it seems like you want to tell us something, what is it?

I don't think many Asian people really want to be called yellow, regardless of whether it makes it easier to read a map.

Because it offends people. It may be unreasonable, but it means that some people will be turned off from the message. Some will take it as a sign that you aren't particularly sophisticated around issues of race.

If you ever want to publish this, don't make Asian people yellow and Indian people red.
