In this geometric exploration, Costa utilizes a vertical format to stack weight and light. The composition relies on the deliberate transition from a saturated, earthy orange into a deep, resonant blue, creating a visual tension that mimics the shift from day into night. By blending the sharp logic of modern illustration with the soft transparency of watercolour, the artist allows the pigments to breathe within their structured environment.

Every inch of the surface serves the study of color theory and balance. The acrylic application provides a matte stability that grounds the more fluid elements, ensuring the geometric forms remain crisp while the internal gradient feels alive. It is a quiet meditation on how simple shapes can hold vast emotional depth through the careful calibration of tone and saturation.
