Is Ensembl transcript color available through ensembldb?

I especially want to know whether it is gold colored: i.e. in both HAVANA as well as ENSEMBL

E.g. IQCC-202.

No, color information or whether a transcript is both in HAVANA and ENSEMBL is not provided by ensembldb EnsDb databases. You can however get transcript support level (TSL) for each transcript in column "tx_support_level":
