Well, as many people say Red is the color of love, its bright, and brings happiness in your life! 😛 So, most brides are mostly wearing Red.
About the Henna, I don't know if there is an actual reason behind it, but again people say the darker the color of the henna comes out, the more your husband loves you. 😕

well in ma opinion mehendi brings good luck to the bride n red dress is the custom since our great great great great grand parents but its not necessary as i have heard it

well,incase of red clothes,i think its just a tradition of a certain people...not all the people are wearing red,some of them are wearing green,esp in gulf countries on their nikkah day....and 4 their beliefs,green is the colour of happiness.....some of them are wearing white gowns.... 😊
while mehndi,can be a part of tradition too....most asians use this tradition....in any happiness,a woman can apply mehndi. 😛
