The color of the spark coming from the coil does not depend in ANY WAY on which way the distributor is pointing nor the direction the rotor button is pointing. It doesn't care, the spark is made by the coil and the TFI module on the side of the distributor body, under the bowl.
You can pull the distributor out of the block and make it point any which way you want, and put it back into the block, and as long as the rotor is pointing near to #1 plug wire when the #1 piston is near TDC on the compression stroke, the engine will likely fire.
Sometimes things get out of sync, so the #1 mark on the cap is too far clockwise or counterclockwise from where you want it to be, and you cannot rotate the distributor body enough without running into something else to get the timing set correctly. You then have to remove the distributor, rotate the body where you want, rotate the rotor to point to near #1, and then re-install the distributor into the engine. When you put it back in, you will find that the rotor turns a bit as it lowers down into place. You must take that into account when figuring out where to make it point by rotating it in the opposite direction and then putting it in. The oil pump is driven by a hex-shaped drive from the bottom of the distributor. The hex may not line up with the distributor shaft, keeping the distributor from going in completely. No problem, just finger tighten the hold-down bolt, and crank the engine over a few turns. The load of the oil pump should make the shaft resist turning enough so much that the distributor drive shaft can turn, and drop down into place. After you get it into place you can set 'static timing'.
Get the crank rotated to 10 BTDC on the timing marks. Pull the #1 plug wire, put a spark plug in the wire and make sure the shell of the spark plug is grounded. Get the rotor pointing to near #1. With the ignition key "ON", rotate the body of the distributor past where #1 is, and then slowly rotate it back towards #1 position. You should hear the spark plug go "tch" as you have just made the TFI fire the coil. When you get the noise, stop moving the distributor. It has just fired at 10BTDC, and if you tighten the hold down, it should start right up.
What you are doing is rotating the sensor past the distributor shaft, just as if the mechanism was turning, but turning the pickup in the bowl, rather than the interrupter on the distributor shaft. The TFI doesn't know, so it sees its signal, and fires the coil. Normally the shaft turns, and bonks the sensor, and that in turn tells the TFI to fire. You are just turning it on its head, moving the sensor relative to the shaft. Works for ignition systems using points, too. Then, you can hear the points make the noise as they open up, collapsing the field in the coil and generating spark.
The engine will run crappy until you get the fresh gas into the injectors. It needs to be run for a while, with all plugs firing, with fresh gas, and reaching operating temperature, especially if it has been sitting long enough to turn fuel into gum.
