Visual assessment remains one of the "gold standard" methods of assessing skin color and a number of tools are currently available to reduce the interobserver variability. Ultraviolet light examination remains a mainstay of the assessment of pigmentary disorders, while polarized light photography is useful for the appraisal of dermal changes, in particular those related to vascularity. With the introduction of modern instruments, reflectance spectroscopy using tristimulus colorimeters or narrowband spectrophotometers provides a convenient, objective, and reproducible methodology for the evaluation of pigmentation and skin color. In vivo confocal scanning laser microscopy is a powerful technique for the examination of pigmented lesions, which shows promise in the detection and diagnosis of early melanoma. Dermoscopy is also useful for the differential diagnosis of benign melanocytic lesions and melanoma, and its use has been shown to significantly improve diagnostic accuracy.
视觉评估仍然是评估皮肤颜色的“金标准”方法之一，目前有多种工具可用于减少观察者间的变异性。紫外线检查仍然是色素性疾病评估的主要手段，而偏振光摄影对于评估真皮变化很有用，特别是那些与血管相关的变化。随着现代仪器的引入，使用三色比色计或窄带分光光度计的反射光谱法为色素沉着和皮肤颜色的评估提供了一种方便、客观且可重复的方法。体内共聚焦扫描激光显微镜是检查色素性病变的强大技术，在早期黑色素瘤的检测和诊断中显示出前景。皮肤镜检查对于良性黑素细胞病变和黑色素瘤的鉴别诊断也很有用，并且已证明其使用可显著提高诊断准确性。
