Razer deathadder elite - Logo LED colour isn't good on white

Hi, On my deathadder elite mouse, the LED inside the razer logo can't be white even if I put the #FFFFFF on Synapse, it goes on a light yellow. But the LED under the mousewheel is white at #FFFFFF. We can't see that much difference on the picture... I tried to update Synapse but it's already updated so I don't know what to do.. Thanks for future answers!
