Mid-key values give Ioannis Altamouras its characteristic quietness - nothing blazes, nothing disappears. Ioannis Altamouras tilts toward cool - blues and silver-greys carry the structural weight. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #0B5D8F at 18.9% is both the most chromatic and one of the largest colours in the palette - chroma as mass rather than as highlight. Value range is moderate at 54 units - enough contrast for legibility, not so much as to fragment the tonal unity. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 4 of Ioannis Altamouras's sequence - a single chapter in a chromatic story told across many works.
