Studio humidity and warmth in Easel by Zaweba
Humidity and warmth are studio climate settings in Easel by Zaweba that change how paint behaves. How a studio's climate affects drying and flow.

Ask a watercolourist about the weather and you will get an opinion. On a damp day washes stay wet for ages and bleed further. On a hot, dry day they set before you have finished laying them. Oil painters notice it too, and acrylic painters feel it most of all. Easel by Zaweba recognises this with two studio climate settings, humidity and warmth, which change how paint behaves.
Why the studio matters
Paint is a liquid that dries. How fast it dries, and how far it moves before it does, depends on the air around it. Warm, dry air takes water away quickly. Cool, damp air holds it back.
That affects almost everything in a wet painting. How long you have to blend. How far a bloom spreads. Whether a wash pools and drips on a tilted canvas or sets in place. How soft the edges are. Easel's paint is built to behave like the real thing, so it makes sense that the studio climate has a say.
Choosing a climate for the job
Think about what you want from the paint, and about how real paint responds to a room.
In a real studio, if you want long, slow blends, lots of time to work wet into wet, and soft edges, a damper, cooler room suits you. It is the climate for misty watercolours and soft oil portraits.
If you want crisp edges, quick layers and less spreading, a warmer, drier room suits you better. Try both settings in Easel and watch what changes. It is the climate for sharp, graphic watercolours and fast acrylic work.
Neither is right or wrong. They are different ways to paint, and real painters often wish they could change the weather to suit the picture. In Easel you can.
Climate and the other drying controls
Humidity and warmth work alongside the other drying tools. The drying speed slider runs from 0.25 to 4 times. Dry now locks wet paint in place straight away. The hairdryer speeds up drying, the dry brush dries one area, and the water brush adds water to wet work.
A sensible way to think about it is that climate sets the mood of the whole session, and the other tools make local adjustments. Set the studio for the kind of painting you want, then use the hairdryer or water brush for individual areas.
Climate and tilt
Climate also shapes what happens when you tilt the canvas. Wet paint runs downhill in proportion to how wet and thin it is, so anything that keeps paint wet for longer gives it more time to run. If you want long drips and runs, give the paint the conditions to stay wet. If you want just a short run, give it conditions to set quickly.
Learning from it
One of the nicest uses for these settings is learning. If you paint for real, try the same wash in Easel with different climate settings and watch the difference. It is a quick way to understand why your real paintings behave differently on different days, and what to do about it.
Keep notes on the settings you like. Over time you will find a few combinations that suit your way of working, and Easel by Zaweba becomes a studio set up exactly the way you prefer it.
