Colorfastness & Longevity
Practical performance of 3.0-4.5 ratings:

• 3.0: ΔE=4.5 after 2 years (visible change)

• 4.5: ΔE≤2.0 after 5 years (instrument-detected only)
  Choose acrylic/polyester in navy or olive for main hues to minimize perceived fading.

Environmental Coordination

• Coastal: Acrylic in slate grey + indigo reflects 60% UV rays

• Woodland: Spun polyester in moss green + tan creates natural gradients

• Modern: Olefin in pure white + charcoal grey – pair with shade structures

Pattern Optimization for 1.5m Width

• Stripes/checks: Align patterns widthwise to reduce waste

• Large florals: Show complete motifs per fabric panel

• Gradients: Maintain horizontal continuity

Color Psychology

• Red/Orange: Stimulate appetite (use 4.5-rated acrylic)

• Blue/Green: Enhance relaxation (ideal for polyester umbrellas)

• Beige: Expand spatial perception (recommend olefin for small patios)

Case Study
A resort used 1.5m polyester with vertical stripes, increasing pavilion visual height by 30%.

FAQ
Q: Do dark colors fade faster?
A: Dark hues absorb more heat – choose ≥250g/m² acrylic and apply UV protectants biannually.
