the ability to have colored each line of the scale musical in a different color
I search for a specific functionnality for childern who have a kind of "vertical dislecxy" : vertical confusion when reading a score , for example the note A are confused with F or C note.
a way for these kind to help them is to set vertical colored reference, in coloring the staff with different color
So the idee is to set each line of staff in a different color, to create this "vertical colored reference": for example the 1rst horizontal line of staff could be blue , the second in red, the third in yellow and the 4th in green (to be choosen by the kind - but the ideal is to be chosen in "complementary colors"
I hope my request will be understandable.
