## Questions & Answers

**Q: Will this paint let plenty of light through transparent plastic as in just make it light up blue?**
A: Sorry - I have no real idea. I think it would depend on the plastic. The super shiny types make the paint separate into puddles but other types allow the colours to spread evenly across the surface. I hope you get what I am on about! It may be a case of trial and error.

**Q: Can this be washed off?**
A: It depends on what you mean by washes off. It will wash off your palette with water, and maybe a little washing up liquid, even after weeks of being there. It's advisable to wash it off your brushes as soon as you can, and also your clothes. But it is much easier to clean up being watercolour than if it was acrylic or oil paint.

**Q: Are these tubes good for making your own watercolour pans?**
A: Yes they are. Squeeze them on to the palette or empty half pan and they will set like tube watercolours but can easily be used when wetted, as with solid half pan colours.

**Q: What size is this.. the picture of the tube says 21ml, the title says 8ml, the description says 21ml?**
A: Hi, the tube I bought is 8ml.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Reasonably priced and great quality!

Great paint - as always from W&N!

### ⭐⭐⭐⭐⭐ Tried and tested

Great quality thanks

### ⭐⭐⭐⭐ Beautiful Transparency
*by R***T on 1 May 2023*

Although this is not a premium brand watercolour, it is nonetheless a very beautiful tube of paint - rich in tone and gorgeously transparent. This 21ml tube is a real bargain, too. Opaque yellows are a bit of a mess sometimes in watercolour paintings, particularly when used in skies or landscapes. Raw Sienna is pretty much a paint box essential, and at this price it's a must-buy, I think.
