I landed at lzu to pick up an instructor for my BFR. After picking up the instructor, I called tower to get permission to taxi to departure runway. Tower said 'you are cleared to taxi via taxiway D to runway 25....' I began taxiing from the FBO ramp. There is a large, nonstandard sign erected at the juncture of 2 txwys. This sign is yellow backgnd with black letter 'D.' because this sign is close to the taxiway junction and because it is not standard per aim 2.3.9, I got confused and thought taxiway D was the crossing taxiway and I turned the aircraft left to enter it. The controller scolded me for not using taxiway D, then told me to proceed via another route. No aircraft conflict arose, there was no other aircraft on taxiway at the time. Conclusion -- taxiway signs should conform to aim paragraph 2.3.9 (black backgnd with yellow letter, surrounded by yellow box). The lzu sign(south) are yellow backgnd with black letter and no surrounding box. This confused me. Also, sign should be set back from crossing taxiway. Unfamiliarity with the airport was a factor. I should have asked for progressive taxi instructions.

Title: PLT OF A PIPER PA22 TURNED THE WRONG WAY DURING TAXI OUT FOR TKOF, RESULTING IN GND CTLR ALERTING HIM TO THAT FACT AND AMENDING HIS TAXI INSTRUCTIONS FROM THAT POINT ON.
Narrative: I LANDED AT LZU TO PICK UP AN INSTRUCTOR FOR MY BFR. AFTER PICKING UP THE INSTRUCTOR, I CALLED TWR TO GET PERMISSION TO TAXI TO DEP RWY. TWR SAID 'YOU ARE CLRED TO TAXI VIA TXWY D TO RWY 25....' I BEGAN TAXIING FROM THE FBO RAMP. THERE IS A LARGE, NONSTANDARD SIGN ERECTED AT THE JUNCTURE OF 2 TXWYS. THIS SIGN IS YELLOW BACKGND WITH BLACK LETTER 'D.' BECAUSE THIS SIGN IS CLOSE TO THE TXWY JUNCTION AND BECAUSE IT IS NOT STANDARD PER AIM 2.3.9, I GOT CONFUSED AND THOUGHT TXWY D WAS THE XING TXWY AND I TURNED THE ACFT L TO ENTER IT. THE CTLR SCOLDED ME FOR NOT USING TXWY D, THEN TOLD ME TO PROCEED VIA ANOTHER RTE. NO ACFT CONFLICT AROSE, THERE WAS NO OTHER ACFT ON TXWY AT THE TIME. CONCLUSION -- TXWY SIGNS SHOULD CONFORM TO AIM PARAGRAPH 2.3.9 (BLACK BACKGND WITH YELLOW LETTER, SURROUNDED BY YELLOW BOX). THE LZU SIGN(S) ARE YELLOW BACKGND WITH BLACK LETTER AND NO SURROUNDING BOX. THIS CONFUSED ME. ALSO, SIGN SHOULD BE SET BACK FROM XING TXWY. UNFAMILIARITY WITH THE ARPT WAS A FACTOR. I SHOULD HAVE ASKED FOR PROGRESSIVE TAXI INSTRUCTIONS.
