Tranquility is from the Affinity collection. So, unlike the Color Preview deck, the colors aren't literal let-downs and are not on a strip.

However, the BenM site offers mathematical suggestions for similar colors and other shades. Castle Walls would be the first one I'd personally choose to sample to work with Tranquility.

Here is a link that might be useful: More shades

Thanks...
That's the Beauty of Tranquility ...It can lean towards blue to blue-grey....depending where it is on a wall, how the light is playing on it...and what it up against. Or if paired with Castle Walls...it leans towards the green hue.
I think I am wanting to stay in the blue-grey tone...so need something that will complement it....Any suggestions?
But the more I think about it...a shade such as Castle Walls would work also..
