for under $175 you are likely to be only able to get a tn panel. an e-ips would be what i would prefer to recommend but your budget most likely does not allow it.
i would stick with major brands such as dell, viewsonic, asus, acer and read reviews on the model before you think about purchasing. if at all possible view the product in person.
led backlighting on cheap models (products in your price range) can often give a blue or purple tint to the display. i have heard that this can be adjusted out.
as far as warm colors are concerned you can change your color properties in the monitor osd settings.
if you want vibrant colors then you want a glossy screen. the tradeoff is that any glare is killer on your eyes.
