The color properties observed at the InSight landing site by the lander cameras are spectral mixtures of two source materials: gray‐black rocky material with chromaticity values of x = 0.32, y = 0.32 (standard deviations of σ_x = 0.02 and σ_y = 0.03) and yellowish‐brown dust with chromaticity values of x = 0.42, y = 0.36 (standard deviations of σ_x = 0.02 and σ_y = 0.03). These results are consistent with published values from other Mars landed missions. The InSight measurements also include the first published value of the white point of Mars daylight, chromaticity of x = 0.35, y = 0.34 (standard deviations of σ_x = 0.01 and σ_y = 0.02), which is redder than earth daylight by δx = 0.04 and δy = 0.01. InSight measurements also show a small color difference (δx = 0.02 and δy = 0.01) between the near field terrain (within 20 m of the lander) and the far field area beyond. This color difference is believed to be caused by dust being blown off by near field terrain by the lander rockets during the landing event. The visual difference between these two regions is caused primarily by the brightness variation. Chromaticity measurements of the Martian sky also match previous missions with additional variability caused by differences in dust loading and the dynamic nature of the Martian atmosphere.

火星InSight着陆点的颜色属性

由着陆相机在洞察着陆点观察到的颜色性质是两个源材料的光谱的混合物：灰黑色的岩石材料的色度值X  = 0.32，ÿ  = 0.32（标准偏差σ _X  = 0.02和σ _ÿ  = 0.03 ）中并用的色度值黄褐色灰尘X  = 0.42，ÿ  = 0.36（标准偏差σ _X  = 0.02和σ _ÿ  = 0.03）。这些结果与其他火星登陆任务的公布值一致。InSight测量还包括火星日光白点的首次发布值，x的色度 = 0.35，ÿ  = 0.34（标准偏差σ _X  = 0.01和σ _ÿ  = 0.02），其比土白天更红ΔX  = 0.04和ΔY  = 0.01。InSight测量结果还显示出较小的色差（δx  = 0.02和δy = 0.01）在近场地形（着陆器20 m内）与远场地形之间。该色差被认为是由着陆事件期间着陆火箭在近场地形上吹走的灰尘引起的。这两个区域之间的视觉差异主要是由亮度变化引起的。火星天空的色度测量结果也与以前的任务相匹配，这是由尘埃载荷差异和火星大气层的动态性质引起的额外可变性。
