[AhyoungRyu]

Addresses https://sendbird.atlassian.net/browse/CLNP-3254

Change Description

Users who want to customize the color set can use below new more descriptive color name instead of 001 / 002 ... 005. I added a color map parsing util function; mapColorKeys to ,a the new & existing color name but we'll be still using the existing names. Refer to this Slack thread for more detailed discussion.
