歼-20和歼-35作为中国第五代隐身战斗机的代表，其涂装设计不仅体现美学考量，更融合了隐身性能、作战环境适应性与战术需求。首先，歼-20通常采用深灰色或接近黑色的低可视度涂装，这种色调有助于在高空或夜间环境中降低被目视发现的概率，同时配合其雷达吸波材料和外形隐身设计，进一步提升整体隐身能力。此外，部分歼-20原型机或早期量产型曾使用过浅灰色涂装，但近年来服役型号普遍趋向更深的灰色系。相比之下，歼-35（原称FC-31）多采用中灰色或浅灰色涂装，整体色调比歼-20更明亮。这种选择与其舰载作战定位密切相关——海军舰载机常需在海洋背景下活动，浅灰涂装能更好地融入海天交界处的光线环境，提高视觉隐蔽性。同时，歼-35作为外贸与自用兼顾的机型，其涂装也需考虑国际市场审美与多用途适应性。值得注意的是，两款战机的涂装均采用特殊隐身涂料，不仅能吸收雷达波，还能抵抗高湿、高盐等恶劣环境，尤其对舰载型歼-35尤为重要。总体而言，歼-20偏重空优与纵深打击任务，涂装强调低可探测性；而歼-35侧重多用途与舰载部署，涂装更注重环境融合与多功能适应。
As China’s representative fifth-generation stealth fighters, the J-20 and J-35 feature paint schemes that reflect not only aesthetic considerations but also integrate stealth performance, operational environment adaptability, and tactical requirements. The J-20 typically employs a dark gray or near-black low-visibility paint scheme, which helps reduce visual detection at high altitudes or during nighttime operations. This color complements its radar-absorbent materials and aerodynamic stealth design to enhance overall stealth capabilities. While some early prototypes or initial production models used lighter grays, recent service variants have consistently adopted darker shades.In contrast, the J-35 (formerly known as the FC-31) commonly features medium or light gray paint, appearing noticeably brighter than the J-20. This choice aligns closely with its intended role as a carrier-based aircraft—operating against maritime backgrounds, where a lighter gray better blends with the sea-sky horizon, improving visual concealment. Additionally, as a platform designed for both domestic use and export, the J-35’s paint scheme also considers international market preferences and multi-role adaptability.Importantly, both aircraft utilize specialized stealth coatings that not only absorb radar waves but also resist harsh environmental conditions such as high humidity and salt exposure—particularly crucial for the carrier-based J-35. In summary, the J-20 emphasizes air superiority and deep-strike missions, with paint optimized for low observability, while the J-35 prioritizes multi-role flexibility and carrier operations, featuring a scheme tailored for environmental blending and versatility.
