Mixing metals + Pre-mixed coolant in water-cooling loop

[Bounti]

Hello! I have a question regarding the different blocks and the coolant I'll be using in my build. The first question is whether the following blocks will cause any issues at all in terms of compatibility.

Secondly, I'm a little concerned about the coolant I'll be using in the loop. Initially, I was going for distilled water and a silver coil, but after reading Koolance's warranty that warns against mixing nickel and silver, I have reconsidered. The decision gets trickier when the color of the tubing or coolant must match my Asus Z87 Pro brown/and or gold color scheme.

Here it is:

It's between finding tubing that matches this theme + using distilled water and a silver coil

Getting clear tubing and using a pre-mixed gold colored coolant.

Thank you so much for taking the time to help me out!

Youtube the pre mixed gold coolant before you consider it XD that's why i kinda recommended against it

I didn't get any relevant videos. I'm looking for some help regarding the compatibility of the components and recommendations on tubing + coolant. Thanks.
