The thinnest bearing is red, followed by pink, yellow, green, brown,

black, and blue. If you looked at the chart I provided in my last reply,

you'll see that the bearings are graduated in .0002" increments.



So if you replace a green half with a brown, you're decreasing the

clearance by .0002", if you go with two browns, the difference would be

.0004".



Now, if you're trying to beat the plastigauge ritual, forget it. You do

it until the clearances are what they need to be, or you can worry

yourself sick over the life expectancy of your engine once it's in the car.


Try going to brown bearings in the caps for the journals that are

currently green (leave the green bearings in the block.) Take a green

bearing and place it in the cap instead of the yellow. Measure the

clearance.


We like to see .0015" -.0017".


Splitting the colors is an accepted way of achieving the numbers you're

looking for.

Also, mixing colors (2 different bearing sizes) on the same journal is never a good idea...it will not allow that portion of the crank to spin concentrically and possibly lead to premature bearing failure.
