Political party colors should correspond to actual usage IRL, as per WP:RS. Currently, some do, and major old ones, don't.
These political party colors have become entrenched for decades. For example, the colors of the Nacionalista Party, Liberal Party and Lakas-CMD have been in use since at least 2006, and has been instituted on this discussion, involving two people, one of whom is me. None of the colors that was adopted by then look to be viable by now.
Some newer parties post-2006 have had it's colors approximate real-life usage, but these also have to adjust to the existing ones, so they do not always check out with usage IRL.
There were efforts to update these, some were implemented, but were reverted because these colors have been entrenched for decades and changes have to be done everywhere in a short span of time, even on images, and this cannot be easily done.
Discuss if any of the colors used have to be changed.
If these are to be changed, to which hexcode.
If there is an agreement to this, images have to be changed first. All of the images have to be identified, and all of these have to be changed.
Once all images are identified, and new images are produced, these can either replace the current ones on file, or new images can be uploaded. If these can be changed to vector files, the better.
Once the images are being uploaded, the hexcodes here have to be changed immediately.
We only have a limited number of hexcodes, and only a limited number of hues a human eye can distinguish with minimal effort.
Political parties that have not competed against each other can have similar colors, but those that did have to be different.
Most political parties have existed in certain eras only. In modern Philippine political history, these are as follows:
American era (1907-1946)
Third Republic era (1946–72)
Fourth Republic era (1978–86)
Fifth Republic era (1987–present)
Some parties will have "dibs" on particular colors. Divided into eras, these are:
American era: There have been two contending forces at this time: the Nacionalista Party, which used red, and those opposed to them, which primarily used blue. The communists also used red at this time. Only the Nacionalista Party is existing from this era, and the party has had several splits at this time, and both should ultimately use the same red hues as the mother party.
Fourth Republic era: The Kilusang Bagong Lipunan (KBL) used red, and the Lakas ng Bayan (LABAN) and United Nationalist Democratic Organization (UNIDO) that both used yellow. So, these are similar to the ones in an earlier era, and the parties from the Third Republic still contested elections with and against these new parties, so we'd have to distinguish them.
Fifth Republic era: Currently, there is a multi-party system. This is a problem because there's a lot of them, and some used colors that are similar to the old parties, and old parties started using new colors.
During the Second Philippine Republic, KALIBAPI was the sole political party, did not compete with other parties in elections, and did not compete in further elections after 1944. No change will be done for KALIBAPI's color, which is based on its party flag.
