着色服务定价通行按面积 + 难度系数：平面件 80–150 元/㎡，浮雕件 ×1.5，双面 ×1.8，含两道封护。经营核心是色样手册：用同一批板材做 30–50 块 100×100 mm 标准色板（编号如 S-Fe-03 = 硝酸铁第 3 梯度），每板记录试剂、浓度、温度、湿度与道次。客户确认色板后按色差 ΔE ≤ 5 交付验收，超差返工费用条款须写入合同，可减少约 80% 的色差纠纷。
Patina services price by area with difficulty factors: 80–150 RMB/m² for flat work, ×1.5 for relief, ×1.8 double-sided, two seal coats included. The core asset is a sample book: 30–50 standard 100×100 mm panels from one sheet batch (coded S-Fe-03 = iron-nitrate gradient 3), each logged with reagent, concentration, temperature, humidity and coats. Deliver against the approved panel at ΔE ≤ 5 and write rework liability into the contract — it removes ~80% of color disputes.
