Yeelight 1S lightstrip color between blue and green does not work

The color of my Yeelight 1S lightstrip when set to a mint color (between blue and green) is just a white color, it does not have the blue-green color it supposed to have :frowning:
My software version is 2.1.7_0018, which is the lastest possible.
Anyone have the solution please helpp, because I really like that color.
