'Green colored oil' on my 1993 case 580 Super K oil pan dipstick

Hello all. Went to check the oil on my Super k turbo and the oil on the oil pan dipstick was green. I smelled the oil on the dipstick and couldn't detect any diesel smell to it. I wondered IF it was antifreeze in the oil but the hoe isn't making any smoke and there is no sign of any milky look to the oil. I haven't changed the oil and oil filter yet, that will be done in the next week or so. Anybody have any ideas of what this might be, what I need to check and how to fix it? I sure...
