This motivated scientists from Mexico, Spain and England to study the luminance in Van Gogh's paintings in detail.

受到启发的墨西哥、西班牙和英国科学家们决定详细地研究梵高画作的亮度。

The effect is caused by luminance, the intensity of the light in the colors on the canvas.

这种效果源于亮度的不同，即画布上不同颜色反光强度的不同。

The more primitive part of our visual cortex, which sees light contrast and motion, but not color, will blend two differently colored areas together if they have the same luminance.

我们视觉皮初级的部分能区分光强以及感知光的运动但不能感知颜色，所以如果两个不同颜色的色块有相同的亮度，就会被混在一起。
