Bloore is best known for his bare palette, his symbol-like forms, and his use of light, texture, and space to invite viewers into a contemplative relationship with his works. According to Terrence Heath, "For Bloore, painting is primarily about image making, it is iconography. And, although the image may or may not be representational in the sense of signifying a perceived reality, it is nevertheless a meaningful sign in a visual language. The image is about content, not form for its own sake."
This approach was largely informed by Bloore's interests in archaeology and the idea of visual laguage, as well as his travels abroad. The artist's all-white paintings in raised relief followed his trips to Greece, Egypt, and Turkey in the summer of 1963. Michael Brodzky describes Bloore's Sumi ink drawings as "a kind of Rosetta Stone, or more appropriately, like the Disk of Phaistos, a codex pregnant with visual significance but without any known verbal equivalent."
Roald Nasgaard makes a similar observation of Bloore's work, writing that "His floating images, exploding stars, broken lines, textured spaces, circles, nets, lines, and arches, his discontinuities, polishings, and scratchings, his monochrome paints and inks of many colours...all aspire to the iconic significance of the great images of other civilizations."
