Testing screen samples like this can still be a helpfull thing to see what you prefer in your room. Keep in mind that side-by-side testing will almost always make the brightest samples look better than any dimmer samples for most content..so seeing what you like both side-by-side and with a few different samples each alone can both give you valuable information.
The sample pack from carlofet includes several different materials for around $5-$10. Some of the most important to look at will be FlexiWhite (which can give you a good idea of whether a plain white screen will work well), FlexiGrey (which will show you a lower-gain light-grey screen) and Carls ALR (which is a dark-grey screen with boosted peak-gain up a little beyond 1.0gain peak).
For rough reference to mississippi's SilverFire paint, the ALR material is darker-colored with similar peak-gain while FlexiGrey is more similarly-colored but has lower peak-gain.
You can also use a mix of PPG untinted silver metallic and a small amount of lighter flat-grey paint to make your own painted screen that looks and performs like SilverFire, but it'll have to be sprayed to look like a sprayed SilverFire screen while rolling it will only look like a rolled SilverFire screen which isn't recommended.
A close match to the regular version of SilverFire with little/no additional colorant would be a mix of:
-30oz PPG tintable silver metallic (shaken at the store but left untinted...about $22 at HomeDepot)
-5oz flat interior paint tinted "Granite Grey" or "OONN 37/000"
or you can obviously use much smaller amounts for painting a smooth test panel:
-6oz PPG tintable silver metallic (shaken at the store but left untinted...about $22 at HomeDepot)
-1oz flat interior paint tinted "Granite Grey" or "OONN 37/000"
If you're aiming to match the even lighter-colored SilverFireNC mix you can use:
-4oz PPG tintable silver metallic (shaken at the store but left untinted...about $22 at HomeDepot)
-1oz flat interior paint tinted "Pebble Grey" or "Veil" or "OONN 53/000"
IF you're rolling SilverFire, then SilverFireNC is the more common recommendation, though it's still best to spray.
HomeDepot sells Glidden and/or PPG 8oz testers of Flat-finish paint for $3-$4 at the paint desk that you can have tinted to these colors (or practically any other color). This and a quart of the PPG tintable metallic can make testing different paint mixes pretty affordable if you'd like to see some mixes that the screen samples like the Carl'sPlace samples can't closely match.
I even have an organized little list to help show what amounts of metallic gives how much peak-gain and about how dark-colored the common neutral greys look compared to each other...so feel free to ask if that sounds like something you'd like to try.
