Do remove this text in Section 3 - The color TLV is ignored if it shows up in the LSP Object of a message where the PCEP Path Setup Type [RFC8408] is Segment Routing or SRv6. And add text to handle the case when both Color TLV and I-D.ietf-pce-segment-routing-policy-cp are present on the receiving side. I guess ignoring Color TLV and logging it could be a good way to handle it. Thanks!
