Sounds like you are directing your question to someone in particular but you don't specify. For a 'guarantee' safety go with 1/4" thick tempered glass, and the lawyer in me says i cannot and will not absolutely guarantee absolutely safety at absolutely at all absolutely all times.

Window guards.

listen dude, u hv a pretty nice design on your doors so I would suggest that you remove that grill (jalli) and instead of these jallis put some coloured glass ,and then paint it "off white" it will look much better that way , thank you

The Color of the glass depends upon the user : 01) Generally people prefer for clear glass to solve the purpose of opening. 02) Go for tinted shade films to match the facade , plays with transparencies, Solar reflective films etc. That again with the purpose of opening . General variant available are in shade of blue green. 03) Then comes the tinted colored glass , that have varieties and options in color . can go with several permutations and combinations of colors in one frame itself.
