有的网友就认为费德勒说错了。
"Roger Federer is wrong" declared one Twitter user, while another suggested that they are a type of "fluorescent yellow" that can also be seen as green.
“罗杰•费德勒是错的”,一位推特用户宣称,另一位则表示它们是一种“荧光黄色”,也可以被视为绿色。
And the emoji adds further weight to the debate, clearly green in colour.
而表情符号中绿色的网球让这个争论愈发热烈。
So, who's right? Well, both parties could actually be.
那么,到底谁是对的?其实,双方都可能是对的。
The official verdict from the International Tennis Federation (ITF) says 'the ball shall have a uniform outer surface consisting of a fabric cover and shall be white or yellow in colour.'
国际网球联合会的官方文件中说:“网球应有统一的外层,表面覆盖织物,应为白色或黄色”。
However, as many have pointed out, the shade commonly used appears to be 'chartreuse', a colour between yellow and green.
但很多人指出,网球的颜色通常看起来是“黄绿色”,介于黄色和绿色之间。
这个问题也引起了专业科技公司的兴趣,研究量子点电视的nanosys公司就用专业仪器测量了一颗网球的光谱,结果显示:
不是黄,也不是绿,而是黄绿。
