Global parameter for changing skin color / hair color

[sam217pa]

Hi,

First of all thanks for the hard work all of you are putting in with asterics grid. I could NOT work without it.

I work with black students, but the default image search refers to white silhouette and pictograms, which could decrease their level of identification and generalization.

It would be very useful if there was a global parameter to change the default skin color of all pictograms currently on a grid or a collection of grid, parameter that could be checked during the image search for images that will be added to the grid.

I like that there is access to this search parameter but it is quite tedious to do it on a pictogram by pictogram basis.

Thanks a lot !
