Racism is deplorable but sad fact is it still exists in much of the world including India.
Since you asked for an explanation I am providing you with one. Kindly do not think that it is my way of thinking or that I condone it in anyway whatsoever. If I go over to US ever .. I will be more than happy to have a beer with you and shoot pool.
Your perplexity at how people as dark skinned as you can exhibit same racism as whites is matched by their perplexity at how people (that is African Americans) born amidst so much wealth and opportunity are the poorest (average income $38,555 per annum poorest income group in USA) while Indians who arrive there stone poor buy a house and send children of to college quite easily (average income $115,200 per annum single wealthiest income group in USA).

The general idea most Indians in US have of blacks is that they are lazy, listen to rap music, consume drugs and are trouble makers.
It is a stereotype that has been prolonged due to black music videos and media
This is US ambassador to United Nations, Nimrata Randhawa from Amritsar Punjab whom you know as Nikki Haley.
US Indians are justifiably proud of her and other successful Indians ..
While Indians lean into US mainstream, African American blacks give themselves strange names like JaMarcus and Da'Shwan (why the apostrophe?) and lean away from US mainstream
Tell me after they watch this video what idea an average Indian American should have about black culture in USA? Answer me truthfully .. considering that for most Indians (here and abroad) getting an A in math and attending a good university is the only goal worth having.
Indians are not being racist towards you inspite of being darker than you .. they are leaning towards the mainstream .. and you are mistaking that as racism.
Since there are lot of Indians who are CEOs of massive companies (Google, Microsoft, PepsiCo, Adobe etc) and who work at highest level in every well known company, bank and universities .. Indians quite rightfully feel that they have made it into US mainstream in 21st century after working their butt off for 50 years. Why would they want to mingle with people who have cornrow hairstyles or have a wife whose sister is called Shabooboo?
(You asked for the explanation so I gave it .. it pained me no end to write it)
About African blacks in India .. it is shameful that people visiting India have been at the receiving end of racism. But I believe it happens only in some parts of India where people are strange in some ways (no other way to put it). Any black is most welcome to Bengal, the most liberal state in India. Several black stay in my locality (students who also play football). No one ever disturbs them.
You are mistaken that it happens only to blacks in India .. it happens to everybody. People from the North Eastern states are persecuted too since they look like the Chinese. We are persecuted too when we drink whiskey at a pub accompanied by a woman wearing sleeveless top. We have our fair share of mentally retarded (living in the Indian equivalent of US Bible Belt)
