I need to produce a map using grayscale (QGIS), as this figure will be printed in black and white.

The map is made up of two layers:

* one cointains the polygon geometry (land cover) - there are five different land cover classes
* one contains the point geometry (facilities) - there are two different attributes, placed on the polygons of the land cover.
They advised me to choose two different symbols for the facilities, I opted for the star and the triangle. But when I have to choose the typology of gray for these 7 different elements (5 land cover classes; 2 point attributes), no solution seems to be enough nice to me.

Do you have any advice?

The biggest challenges is to identify two grays for the point layer which are enough visible.

after receiving your tips the new map - closeup - is[![enter image description here](https://i.stack.imgur.com/dlUPu.png)](https://i.stack.imgur.com/dlUPu.png)
