The invention relates to a highly-resistant-to-color-changing gold anti-corrosion copper alloy and a panel preparing method thereof. The alloy is formed by the chemical components as follows: 77-79wt (weight) percent of Cu, 2.0-2.3 wt percent of Al, 0.4-0.6 wt percent of Ni, 0.005-0.01 wt percent of B, 0.05-0.15 wt percent of Ce, 0.2-0.5 wt percent of Si, and the balance of Zn and inevitable impurities. The preparing process comprises the steps of 1, smelting, 2, semi-continuous casting, 3 milling, 4, hot rolling, 5 milling, 6, cold rolling, 7, intermediate annealing, 8, pickling, 9, cold finish rolling, 10, finish product annealing and the like. The highly-resistant-to-color-changing gold anti-corrosion copper alloy is reasonable in component, simple in production process, low in production cost, excellent in casting and processing properties, suitable for performing batch production by using a semi-continuous casting process, and compared with the existing copper alloy such as HAl77-2B, HSn70-1A, HSn72-1-1, the alloy produced by the method is more close to gold in color, better in color-changing-resistant and anti-corrosion properties, and is applied in the fields such as decorating, energy engineering and marine engineering.
