during my visit in Stockholm I made some pictures but due to the bad light in the museum, most of them were not good made (studid, I know) I can ask for a re-visit to my wife, but I assume she will not approve this visit
During research they color analyzed only a number of key sculptures of all her ornaments, so even when they captured her look, I think there is room for artistic freedom when you paint your model details.
To me it looks like they didnt use shadow techniques when painting the 1:10, but used highlighting colors instead. You may want to do it more subtle for a balanced and realistic looking paintjob, especially at the scale 1:75.
Where we have been able to analyze the paint scheme in detail, it is clear that the original sculptures were painted with highlights and shadows to enhance the detail and surface relief, not just solid colors. When the museum's 1:10 model was first painted, the sculptor who made the carvings wanted to paint them. He did so, but without highlights and shadows, so it was necessary to repaint the sculptures. Many of the pictures on our website were taken before the repainting, and thus do not have the same depth that the model does now.
As Matti noted, we have only analyzed paint remains on about 80 invididual pieces of ornament, and from that extrapolated the overall paint scheme. We tried to get samples from at least one element in a group (thus we sampled one of the 19 surviving ROman emperors from the beakhead very thoroughly), but we cannot guarantee that the group was entirely consistent in its painting, so modelers have plenty of freedom.
The evidence we have for the colour scheme of the ship is the physical remains of paint still adhering to the wood, which has been sampled and analyzed. There are remains of the red background colour in several places. The pigment, like most of the pigments used in this period, are mineral in origin, and so bright, saturated colours were very common for paints if the right pigments could be found. Dyes for cloth in this period tended to be more subdued, since the colouring agents used tended to be vegetable.
The red in this case is a fairly bright red, approaching scarlet. The 1:10 model in the museum is currently painted with colours which we believe are the closest we can come to what we have been able to analyze in hundreds of samples taken from the ship.
