Low hue photobleaching compositions comprising organotin (IV), organogermanium (IV), organoplatinum (IV), organopalladium (IV), organolead (IV) or organophosphorous (III) phthalocyanine and naphthalocyanines having Q-band absorption maxima at wavelengths greater than 660 nm and increased triplet state yields whereby production of singlet oxygen is increased. Use of Sn<4+>, Ge<4+>, Pt<4+>, Pd<4+>, Pb<4+>, P<3+> phthalocyanine and naphthalocyanines compounds in photobleaching compositions allows for formulation of low hue laundry compositions, bleach compositions, and hard surface cleaners.
