You've told dnsmasq to send a lease with option 6 (DNS) set to

are you saying that this
dhcp-option=tag:red,option:dns-server,10.88.13.3
dhcp-option=tag:green,option:dns-server,10.88.13.4
is not defining two upstream servers?
If you'd expect dnsmasq's DNS server to switch its upstream DNS based on
those options, that expectation would be entirely unjustified:
Those lines configure DHCP, not DNS.
That first line instructs the DHCP server to hand out 10.88.13.3 as DNS
server when a red DHCP client is requesting that DHCP information, e.g.
during initial DHCP lease negotiation - likewise the second with
10.88.13.4 for green clients.
A client will then send its DNS queries to that respective DNS server.
S Irlapati, you did force your client to request a new DHCP lease to put
those options into effect, didn't you?
