Origin of term "color coding"

Does anyone remember why the old traffic reduction scheme was called "color coding"? It was only later changed to number coding (UVVRP), right, but it originally started out as a color-coding scheme.

good question, i was still going to school in manila when that color coding was thought up. i just can't remember what the meaning was. di naman siguro pwede light colored cars and dark colored cars?

I think number coding yung rule ever since, kaya lang, color coding yung tawag since mas madali sigurong tandaan dahil familiar na yung ibang tao sa concept of color coding...wild guess lang ito :-)

first time i heard of the term "color coding" was way back in high school. it was in electronics class, when we were studying resistors. The resistance of a resistor was indicated by colored bands around the resistor, each color corresponding to a number then the last band was a multiplier.

i guess the scheme is the same for the "color coding" scheme for vehicles, except wala na colors to memorize, kasi the ending number na ang gamit sa "coding" day mo.

color coding... AFAIK:

the original plan then was to afix COLORED stickers on the windshield of cars to distinguish and segregate them. but this idea was scrapped and the ending plate number was used instead for simplicity's sake.

this was first test piloted on buses but its actual implementation on cars was halted and this was replaced by the UVVRP number-coding scheme.

well, since Filipinos have a penchant for using old terms, hence the name color coding was retained (think calling all films Kodak).

color coding, i remember its the same wd the number coding, if im not wrong na odd no. at even no, ay may correspondent na color sticker na ididkit sa windshield kaso naisip ng LTO dagdag gastos pa sa kanila noon,dahil di pa kasi gaano korakot gov.odpisyal noon, ngayon lang kung may dahilan na mapalabas ang podo kahit d kailangan gagawin. Tulad ng smoke test, drug test dami nagkakapera dyan. Pero may nagbago ba!? Noon ang mga INSPECTOR sa LTO titignan talaga ang vehicle kung dapat pa sa kalye. Noon di lang mabasa Plate no mo hahabulin ka na ng HAGAD, ngayon PAPOGI lang ang mga hinayupak na MMDA. GEMINI na 75 model may plakang starts sa U di nila sitahin, dapat alam nila na lumabas ang U sa mga 95-96 model. Kaya malayang nakalalakbay mga criminals.
