Girl With Hair Ribbon

It was time to do something different with my Lego World Map set (31203). I looked at the Lego Andy Warhol’s Marilyn Monroe set (31197) first. The World Map tiles have ten colors, but the bulk is white and blue/green (building all 4 Marilyn’s impossible).
I then realized there is another color available: black (a place without a tile), So I started to look for a suitable art piece..and found the “Girl with Hair Ribbon”, a 1965 painting by Roy Lichtenstein. I also liked it because it has the Lego primary color scheme.
Creating a mosaic
There are several online tools that help you to convert an image into a mosaic. Basically I tested them all, but one by one they have a limitation (for my purpose).
I then found that Bricklink Studio has an “Mosaic” option! And a very good one. Even with size 48×48 there was an impressive result. In order to get some details better I ended up with 96×96 (my limit with the number of ground plates from the World Maps set).
The only problem: Studio ignores the red dots; it generates the skin all white. Initially I thought of a simple red-white-red-white etc pattern, but it soon became clear that that is too much. So I had to find a better pattern…
So I ended up writing a Python program that translates the image into a 96×96 pattern with a custom “make_skin_mask” function to fiddle with various dot patterns.
Colors
As mentioned above the World Map comes with a lot (light)blue and (3 flavors of) green. Red is critical import in the image, so I ordered red tiles. The hair is a mix of two colors (from the World map set). Wrong if you look at the original, but it gives a ‘dotted’ effect, which is nice. Originally I used pink for the lips, green for the area right and tan tiles for the white area on the girls face. Not totally happy with that I decided to stay with the original (and buy more red)
Possible improvements
I used the round white plates from my World Map set. Obviously they do not give a flat surface. For the white in the eye’s I did use white tiles. I did not use any black tile. I am not sure if it would change much. Especially from a distance (see the office wall picture).

[Ingezonden als Lego idee, echter de limiet is 5.000 stukjes, en daar zit ik ruim overheen. Dit is dus een unieke “1 van 1” geworden!]
