Italian Flag (left) and Mexican Flag (right)

Recently, we hung an Italian-flag
windsock on our deck as a prop for an upcoming party and realized that the colors of Italian flag looked a lot like the Mexican flag on first glance. (A neighbor dutifully noted the windsock and commented that she was surprised because we were not “windsock” people.)
So what are the differences between the Italian and Mexican flags? The
Italian flag is a vertical tricolor (in Italian
Il Tricolore) of green, white, and red. The
Mexican flag on first glance is the same except the there is a coat of arms in the center white stripe. However, there are a couple of subtle differences. The Italian flag uses lighter shades of green and red and the Italian flag has an aspect ratio (width:height) of 3:2 while the Mexican flag is 7:4.
The Mexican coat of arms in the white band of the flag is an eagle perched on a prickly pear cactus with a snake in its beak and talons.
The meaning of the colors for the Italian flag depend on who you ask. One common and poetic interpretation you might hear is that green is the countryside, white is the snowy Alps, and red is the blood spent during wars for Independence. A less poetic but more accurate explanation is that the Italian flag was first created in 1797 during the short-lived Cispadane Republic of Northern Italy. The red and white were already colors of the flag of Milan and green was based on the color of uniforms. The Italian flag was written into the constitution in 1947 as a tricolor: green, white and red in vertical bands of equal size.
The meaning of the colors for the Mexican flag likewise is not fixed, but can be taken to mean roughly: green = hope, white = purity and red = blood of national heroes (as pointed out by several comments below, in particular the comment

The flags for
Ireland and
Côte d’Ivoire look similar to the Italian and Mexican flags, except they use orange instead of red.
