Here is a pic by pic account of my painting of a Vorlon Heavy Cruiser
I used GW paints and Windsor & Newton inks.
I used Calthan Brown foundation paint for painting in the shadows. I deliberately avoided black as I thought it would be too harsh v the yellow.
Three steps difference from pic 1; Step 1 - I ran nut brown ink into the deepest shadows. Step 2 - I painted Golden Yellow over the entire ship running over the Calthan Brown as necessary & Step 3 - I used Bad Moon Yellow as the first general highlight.
Again two steps difference from the previous photo. Step 1 - All Edges highlighted with several layers of a mix of Bad Moon Yellow and White starting at 50:50 mix and adding a little more white each time. Step 2 - i thought the overall look of the yellow was too warm, the canon ship yellow has a much colder tone so I mixed a glaze of apple green/canary yellow ink 1:4 and painted on in two coats over the entire ship.
The tooth brush spray technique: speaks for itself really. Used black india ink diluted 50:50. brush shaken well to remove any lliquid excess, until almost dry before spraying.
(disclaimer:-The fortuitous lettering visible on the paint pot, shown in the above photo is the result of an entirely random event and any relevance to persons living, dead or indeed fictitious is purely coincidental).
The result.
Although the toothbrush process looks risky there are two possible recovery methods. For areas where there appears to be too large a blob a few dots of diluted bad moon yellow soon brings it back. The diluted india ink is also easily removed by water and can be resprayed. (I had to do this on a section on which I accidently dropped some blue ink later in the paint process).
