Thank you for your suggestion. However, it works with context and not with lmtx.

Looks ok here ... but isn't the transparacy used instead of the sizes? Anyway, you can use named colors
```
\starttext

\startMPcode
defaultfont  := "texgyrepagella-regular*default" ;
defaultscale := 0.8 ;

definecolor [ name = "mp:red",   b = 1 ] ;
definecolor [ name = "mp:green", y = 1 ] ;

path twos, threes ;
```
twos := fullcircle xscaled 4cm yscaled 2cm rotated 180 shifted 42 left ; threes := fullcircle xscaled 4cm yscaled 2cm shifted 42 right ;
```
fill twos   withcolor "mp:red"   withtransparency(1,0.5) ;
fill threes withcolor "mp:green" withtransparency(1,0.5) ;

draw twos ;
draw threes ;

label("...",( 1.5cm,0));
label("...",( 0,    0));
label("...",(-1.5cm,0));
label.top("\strut yeux marron",   (-1.5cm,1.25cm));
label.top("\strut cheveux blonds",( 1.5cm,1.25cm));
\stopMPcode

\stoptext

```
(you cannot overload colors at the tex level in mp but use them in order to be consistent)
```
