The whole idea of Camo is the breaking up your out line of human presents and masking any slight movements you need to make. Whether you mix or match camo patterns don't matter and only helps you blend in better at times. Seasons advance fast in Southern Ontario, and the start of a turkey season the woods and terrain are very dull, with lots of grey,black, browns and even a fall leaf orange. It only makes sense to try and match your areas you intend to hunt to blend in and make for better success towards game coming closer without detection.
As the season warms up the leaves start to break out and add a green look to the dull darker colours, so if one can change your pattern colours in camo to match or come close only helps you match in with any setups. By a late May there is far more green then the dull colours so the green is even more important.
Now with this being said it also depends on where you plan on hunting as for a setup location. In a tree stand high above a normal ground setting a sky or lighted patched camo pattern will fit in much better then a dark branch, leaf pattern, Light more open branches and matching colour leafs blend in much better like a Realtree Hardwoods or AP or APG In Green or Grey depending on the time of year.
A ground setup effect and depending again on that time of year, Hardwoods Grey for a lower ground effect with a Max 1 or hardwoods green or APG would help blend you in better.
Now as stated above most game animals are colour blind, so the patterns in a camo pattern just helps you fit in, but if it is Wild Turkey your hunting they DO SEE colour so it is important and better for success to fit in with colour in patterns to setups the best you can.
You do not have to walk out in the woods looking like a Sears Catalog book, mix and match will work as well and even better at times.
