Q: Sometimes everything is only light green or light red. Why?
A: That happens when the values have changed a bit but not significantly. Then the update is not accepted as "true". The colors then only show whether the popularity value itself increased or decreased.

问：有时候只有浅绿浅红是什么情况啊？
答：说明数值只变了一点点点点，热度不算准确，这时候的颜色只表明数值是涨还是跌。
如果翻译正确，那么以后看到红绿网只有浅色那么也就凑活看看颜色吧，至少跌涨还是知道的
