Thank you and you're welcome Tim
Since I started casting and painting land before time figures the coloring has changed quite a bit and I thought it funny to post a little "evolutionary chain" of my two oldest tinfigures.
First we have Ducky (the very first successful cast with that mold is still in my profile):

On the top left is the brooch on which the mould was based (that one is of course not colored by me). Next there is a pure unpainted tinfigure. Next comes one of my earliest paintings which seems to have been influenced more by the colors of the brooch than Ducky's colors in the movie (she appears to be much darker). The other Ducky's (from left to right top to bottom in the order in which they have been painted) are all much lighter than this first one. Her green was changed from a deep green to one with a slightly paler more yellowish tone. Her "yellow belly parts" were also changed from a sandy color to a paler tone. In general it is remarkable how much white one needs to add to the original colors (I am using mostly Revell and Humbrol model painting colors by the way) to "pale them out" enough to resemble the colors in the movies. One of the main differences between the last two figures is that while the last but one is colored in semi-gloss colors while the last one is mostly mat (excepting moist parts like the eyes and the open mouth). Here is a second picture of the Ducky's taken from an angle that allows for a better view on the color changes that took place on Ducky's darker back:

The next evolutionary chain is Littlefoot's:

Again the upper left is the original brooch followed by an uncolored tin sample, and the first figure which seems to have been influenced by the brooch rather than the movies with that strong brown color. The left figure lower row already comes closer to Littlefoot but the color is still relatively strong I think I used quite a few different colors to get that mix together. The next one was relatively simple. I figured out that a mixture of roughly 50% white and rust color will create a color fairly close to Littlefoot's main skin color. The mixture for Littlefoot's lower parts used to be another mixture that was given up for plain human skin color (sometimes I am surprised myself). Again the last but one and the last figure differ mainly in being semi-gloss respectively mat.
