I am using this keyboard. I find browns to be too noisy on the bottom out and the clack they make when they return to top.
The silent reds are very smooth and nice and quiet. But it's not as good for typing. Great for gaming. But when I use muscle memory to type really fast... like long passwords, I get tripped up by the linear reds sometimes.
So I'll be switching to zilents in that board.
Otherwise... the board is SUPER quiet. Its solid. The stablizers are nice and quiet. I've also got it on a deskmat.
But the colors. I wanted the exact same thing as you. All white on the lowest brightness setting.
I used the printed manual that came in the box with the keyboard.
Use Fn + F4 to cycle through the basic modes. There are 6 modes to cycle through as you keep pressing Fn+F4. Four of them are various active modes. One of them is to turn all lights off. One of them is to turn all lights on. So, I just press Fn+F4 until I get the mode where all the keys are just the same color and turned on. Now, it might not be white. So now you have to change the RGB colors to get white. To get the amount of Red you want, you press Fn + F1. I think there are 6 levels of Red brightness. Just press it until you get maximum Red. If you press it one too many times, it will go to zero amount of Red. If you have Zero amount of Red, just press Fn+F1 six times to get max Red. Now do the same with Fn+F2 until you get maximum Green. Then Fn+F3 to add maximum Blue. With maximum Red, Green, and Blue, you mixed together, you will achieve white color.
Now you can use Fn+ the left and right arrow keys to adjust brightness. I turn them down low.
