To change the surface color of oak (Quercus alba L.) to dark and grey, the water-soluble iron ion compounded dopamine solution was applied and accelerated in temperature–humidity condition. The colorimetric parameters before and after treatment were measured and X-ray photoelectron spectra were carried out for a further understanding. The results showed that iron ions and the compounds can significantly cause color changes to the oak, while the compounds treated groups seemed more uniform. With increasing concentration of the colorants, the color change was more obvious. During acceleration in temperature–humidity condition, the oxidation occurred, which further caused color change to oak. However, different oxidation reactions might occur between iron ions and compounds treated groups. The compounds system was more sensitive to temperature–humidity condition. Thus, the color difference was the highest. In a word, this treatment was effective considering the coloring effect and safety process.

改变橡木的表面颜色（Quercus albaL.）涂成深色和灰色，然后应用水溶性铁离子复合多巴胺溶液并在温湿度条件下加速。测量处理前后的比色参数，并进行X射线光电子能谱以进一步了解。结果表明，铁离子和化合物可以显着引起橡木的颜色变化，而经化合物处理的基团看起来更均匀。随着着色剂浓度的增加，颜色变化更加明显。在温湿度条件下加速过程中，发生了氧化，进一步导致橡木变色。但是，铁离子与化合物处理的基团之间可能发生不同的氧化反应。复合系统对温度-湿度条件更敏感。因此，颜色差异最大。总之，考虑到着色效果和安全性，这种处理是有效的。
