The results showed white light and yellow light were good for cultivating strong seedling, blue light, red light and green light in turn.

结果表明，白光和黄光培养壮苗的效果最好，蓝光和红光次之，绿光下徒长。

A quantum-dot display would work by arranging quantum dots that emit red, green and blue light in a grid-like pattern, and getting those dots to emit light directly.

量子点显示技术的工作原理是，通过将散发红光、绿光与蓝光的量子点排列为网状图案，并让这些量子点直接发光。

Combining red, green and blue LEDs to produce white light has the potential to be more efficient, and the colour of the light could be tuned depending on mood or taste.

结合红绿蓝led一起生成白光有能被更有效利用的潜在可能，并且光的颜色还可以依据心情或者口味来调配。

It's no use talking about the negative relationship between a red light and a green light and a yellow, white, or blue one because they all have the same value.

讲什么它是红灯，不是绿灯,不是黄灯白灯一点关系都没有,它们所代表的意义都一样。

The vehicle systems are capable of tasks such as scanning movement of objects around it, identifying a green light from a red light and measuring the trajectory of the vehicle on the road.

The techniques employed might also help to improve LEDs that produce white light by mixing red, green and blue emitters.
