Spectrally-selective monitoring of ultraviolet radiations (UVR) is paramount importance across diverse fields, including effective excessive solar exposure. Current UV sensors cannot differentiate between UVA, B, and C, each which has a remarkably different impact on human health. Here we show spectrally selective colorimetric UVR by developing photoelectrochromic ink that consists multi-redox polyoxometalate an e- donor. We combine this with simple components such as filter paper transparency sheets to fabricate low-cost provide naked-eye UVR, even at low doses typically encountered during Importantly, the tolerance skin colors demands personalized sensors. In spirit, demonstrate customized design robust real-time dosimeters meet specific need phototypes. These spectrally-selective offer remarkable potential in managing our day-to-day life.
