Bob Ross® Phthalo Blue Oil Paint

Bob Ross® Phthalo Blue oil paint is used very often in the wet-on-wet method. Usually, you'll use Phthalo Blue for sky scenes, water, and often as part of the shadow color on snow-capped mountains. If you paint often, the 5 oz Phthalo Blue tube will be the way to go, otherwise, the 1.25 oz Phthalo Blue tube should last you quite a while.

If you cannot find a local retail outlet for Bob Ross® Phthalo Blue then you might consider buying from a reputable, high-volume art supply dealer online. The normal list price for the 5 OZ tube of Phthalo Blue is $17.49 and the 1.25 OZ is listed for $7.29 but you can buy it online for far less.
