# IndexStyle — https://indexstyle.org/compose?ids=celestial-atlas+weather-map

# Style descriptors only. Never imitates a specific artist, studio, brand or work.

An original image that takes its structure from Celestial Atlas (Style, 17th–19th century) and its accent from Weather Map (Style, 1851–). Structural cues: Myth figures over stars; Concentric celestial structure; Gold and blue coloring; Ornamented cartouches. Accent cues, used sparingly: The density of isobars; Cold and warm front symbols; The weather-symbol system; Highs and lows labeled. Composition: Concentric spheres at the center, four corners filled with cartouches. Type and lettering: Title inside an ornamented frame, star names tiny and italic. Let one material quality come from the second style: The base map held pale, only lines and symbols brought forward. Mood: Exhilaration, Luxury, Calm, Trust, Technology. Color: build on #e9e6dd, #67635d, #171615 with a single accent drawn from #e9e6dd, #67635d, #171615. Constraints: do not imitate, reference or name any specific artist, studio, brand, character or copyrighted work. Produce an original composition in the general period languages described above.

# Where the two fight
# - Both belong to Diagrammatic Expression, so the difference is small. Push the roles further apart than feels comfortable.
# - Roughly 1834 years apart. Keep one of them recognisably period rather than letting both drift into the middle.

# Cautions carried from each entry
# - Celestial Atlas: Drawing the myth figures so large that the star positions vanish leaves a plate working neither as diagram nor as ornament.
# - Weather Map: Changing the isobar interval from day to day destroys the cue that lets a reader judge wind strength from how crowded the lines are.
