Lead(II) Chromate = PbCrO4
PbCrO4
Lead (II) Dichromate
You probably mean lead chromate since you have mentioned an oxidation state of 2+ for the lead ion and the chromate ion has an oxidation state of 2-. Lead chromate is yellow. Please see the link.

Chromium was discovered in the mineral crocoite (PbCrO4) - Ural Mountains (Russia).
Pb(C2H3O2) + K2CrO4 > PbCrO4
Na2CrO4+Pb(NO3)2>>2NaNO3+PbCrO4
Solubility in water depends upon attractive force among the oppositely charged ions and their compactness in crystal lattice, the ionic compounds having strong attractive forces among ions and high compactness are insoluble in water as AgCl, CaCO3, BaSO4, PbCrO4 e.t.c
