This is a wood frame house. The bottom two feet or so were finished with some type of stucco over a metal lattice.
The stucco has begun to crack and chip in the corners where instead of there being lattice there is metal right angle brackets.
And in a couple of places cracks have also developed but have not caused any of the stucco to fall off.
What do I use/buy to repair this and how do I go about matching the color as close as possible.
Thanks in advance

You need two materials.
First some liquid bonding agent. The best is WeldCrete by Larsens Products. But get some by QuickCrete because it dries clear
Second you need some mortar mix. You could buy Portland cement and masonry cement or lime and mix your own. Ity is just handier to buy mortar mix. Mix it according to the directions on the bag. Get the smallest bag, 60# I think. It will not take all of it.
Make sure you have any loose stuff removed. Paint the edges of the existing on the corner. Mix up some material to about the consistency of peanut butter and press it into the mesh of the corner bead and well into and behind if you can the edges. Use your trowel to screed it off flush or a little fuller with the existing. Let this get tight. That is firm up some then float it with a sponge float. if it is too green when you do this it will hollow it out. just refill it and wait longer the next time before you float it off. This looks like it is a brown coat only without a colored finish. only with luck can you match the color but you can buy some exterior stucco finish and finish the whole base.
Now about the cracks. You best bet is to wash them out with water pressure then mix up some of the same mix of a thinner constancy and rub it in with the float.
Personally. I discourage messing with cracks. They almost always look worse than a crack.

If the repairs show too much and you decide to paint, an elastomeric paint does a good job of sealing and for the most part hiding hairline cracks in stucco. It would require a primer first.
