I'd highly recommend the LCI ones Herb listed. American made and basically pretty similar to the Scepter ones, which are made in Canada. The LCIs are significantly cheaper; $26 and free shipping if you get two at buylci.
LCI doesn't make 20L ones though, and no black. The olive is pretty dark though. LCIs have a bit of a different lid. The lids on mine sealed well, but you could always buy some gaskets if need be. A seller called jamte sells a bunch of accessories for them on eBay; kinda pricey though. Search my posts and you'll see how I modified mine to deliver water by pressure.
They also sell spare lids, here's a link to a spare lid:

LCI manufactures these mostly to gov't contractors; they're an organization specializing in employed blind people. These are WAY better than the aforementioned POS containers you get from Reliance and others. Might as well use ziplocks. You could probably paint the LCI or Scepters; I think they're HDPE. You could have one black and one tan side, and just turn one or other toward sun.
And once you get water containers with the big mouth you'll never go back to the others. Way more usuable.
