In these harsh economic and meteorological times (yes, it’s STILL hot!) not everyone can afford stuff like this:
To help preserve paints in the heat, and also because mixing that one colour again was a once in a million thing and it’s a shame to have it dry up … let’s have a look at a cheaper DIY solution!
Usually, the palette used is unimportant; a clean piece of plastic will do. Old CDs are a prime candidate in the Mancave for being turned into palettes, “Take THAT, Mariah Carey’s Greatest Hits! Whaaapaa! There’s some Snot Green for ya!!” and so on. The normal palette allows me to mix colours and thin them with my thinning agent of choice. However, over time, the water in water-based paints will evaporate and the paint will dry out rendering it useless! Even under optimal conditions, the drying out of the paint is inevitable, more or less in the extremes of summer heat, in air conditioning and ducted heating. It’s a nightmare!
The amazing cure is the wet palette. Its simple goal is to maintain moisture in the paint at the same rate that it evaporates. Custom colours mixed p on the wet palette remain useable for days after they are originally combined and you can jump straight back into painting with your colours where you left off without having to remix them up again to match your previous work!

Based on the process of evaporation and other factors like humidity, you may see the sponge dry out faster or slower. Keeping the lid on the plastic container between uses will reduce the amount of drying out of both the sponge and the paint on the wet baking paper.
