Transmissive electrochromic light modulators require two electrodes to be in the light path, a primary electrochromic material and a charge-balancing counter electrode (CE). Two insertion-type CEs are reviewed, IrO{sub 2}, for operation in protic environments, and V{sub 2}O{sub 5} for operation in non-aqueous, Li-based electrolytes. Both undergo anodic coloration processes which complement the blue cathodic coloration of WO{sub 3}. Reversible and deep visible light transmission modulation has been demonstrated for WO{sub 3}/IrO{sub 2} and WO{sub 3}/V{sub 2}O{sub 5} series combinations.
