Mid-key values give Joan Brull its characteristic quietness - nothing blazes, nothing disappears. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. The dominant colour, #C89C33, takes 29.7% of the total area, establishing the overall mood before any other hue is introduced. The most saturated colour, #B57721, is reserved to 5.5% of the surface, where it acts as a focal punctuation. Spanning 33 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. Together these qualities point to the open-air Impressionist method: recording light rather than local colour. Joan Brull's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
