Emulsion Woad Paint

I bought some Bleu de Lectoure woad powder from Maiwa.

Bleu de Lectoure also produces ready-made paint tinted with woad, beautifully-looking in the advertising photos.  Maiwa just carried the dyestuffs.

Knowing woad paint was possible made me want to try to make some for myself.  The powder didn't incorporate into the paint that well, though.  The dark blue smudge on the top of the wedge of wood is woad plus boiled linseed oil.  The greyish-blue sides are painted with woad in linseed oil with egg and water.

I wonder if it would mix in better and give a better result if added to regular, ready-made white paint.
