The neon color effect can be described as an illusory spread of color surrounding colored lines embedded in certain line gaps. The effect is seen in the Ehrenstein pattern if colored crosses are added to the central gaps so as to connect the inner tips of the pattern. Experiments were conducted to explore the dependence of this neon color effect on the wavelength and retinal illuminance of the inducing lines. The following results were obtained: neon color effects are strong when the wavelength of the crosses is in the short- (less than 480 nm) or long-wave part of the spectrum (greater than 620 nm) and the wavelength of the Ehrenstein pattern is in the middle-wave part (500-580 nm). Effects are weak or absent when the crosses and the pattern have similar wavelengths. The neon color effect is just detectable when the ratio between the retinal illuminances of the Ehrenstein pattern and the crosses ranges from 0.1 to 0.8. The neon color effect is maximal at illuminance ratios ranging from 0.8 to 8. The strength of the neon color effect is independent of the illuminance level of the crosses if the illuminance ratio to the Ehrenstein pattern is maintained.
霓虹色效应可以被描述为嵌入特定线间隙中的彩色线条周围颜色的虚幻扩展。如果在中央间隙添加彩色十字以连接图案的内尖端，在埃伦斯坦图案中就能看到这种效应。进行了实验以探索这种霓虹色效应与诱导线的波长和视网膜照度的关系。得到了以下结果：当十字的波长在光谱的短波部分（小于480纳米）或长波部分（大于620纳米），且埃伦斯坦图案的波长在中波部分（500 - 580纳米）时，霓虹色效应很强。当十字和图案具有相似波长时，效应很弱或不存在。当埃伦斯坦图案和十字的视网膜照度之比在0.1到0.8之间时，霓虹色效应刚好可被检测到。在照度比为0.8到8之间时，霓虹色效应最大。如果与埃伦斯坦图案的照度比保持不变，霓虹色效应的强度与十字的照度水平无关。
