You're reading too much into it. Colour ink was still expensive back then up until the late '80s to '00s. Which is why coloured photos were uncommon before, especially in the 1960s.
And before anyone suggests it, professional historians strongly discourage colouring black and white photos. This could give false impression of what the actual colour of some objects, or the subject itself in the photo.
I just Googled by the way of your claim, it turns out that the narrative is indeed hamfisted: https://eu.usatoday.com/story/news/factcheck/2020/06/20/fact-check-most-civil-rights-era-images-werent-made-color/3210472001/
Our ruling: Partly false
We rate this claim as partly false because it excludes context essential to understanding the difference in use between black-and-white and color photographs taken during that time period.
Although there is documented evidence of photo suppression during the civil rights movement, experts said the use of black-and-white over color photography was not part of it.
The post is misinformed and overlooks the fact that color photography was rare in the 1960’s due to its higher price, photojournalists’ need for quick turn-around, the sentiment of black-and-white photography being the “true” way of documentation and the challenges surrounding accurately depicting people of color with color film.
Same in Ireland. Over ten years of underfunding services and lack of affordable housing and then over time many refugees are coming in, which competes with the already strained infrastructure. Then in the recent local election, the far-right have gained more influence than before. And yet the media narrative has always been about these working class riff raffs giving the Irish bad name; or Russia amplifying discontent in social media. No one mentions that the working class and homeless have been made to compete with immigrants and refugees, through no fault of their own, are coming from regions wrecked by war, corruption and climate change. This has been a boon for the elites-- having more people create demand for artificially-made scare resources to increase the material value. Hotels are paid enormously by the government for taking in refugees and the owners are all too happy to do so.
