Can anybody with the journeybook please let me know what the official colour scheme is . Also can somebody recommend which journeybook is the best to buy. I don't want to purchase all of them at once

Weapons and Armor: Chainmail

Gold Details: Shining Gold and Brown Ink

Prime in white. Codex Grey mixed with Shadow Grey for base coat. Dry brush Skull White over it.

It looks like the Journeybooks are being discontinued. My honest suggestion is snap up all three used, now, if you have the means.

If not: Starting at the beginning might not be a terrible idea. I'd look around in your secondary market and make some plans.
