And I also have a question about the colors: or more specifically, what is the difference between 'hydrogen alpha emission' that are colored red, and 'hydrogen series emission', colored blue and purple?

<<The visible spectrum of light from hydrogen displays four wavelengths, 410 nm, 434 nm, 486 nm, and 656 nm, that correspond to emissions of photons by electrons in excited states transitioning to the quantum level described by the principal quantum number n equals 2. There are several prominent ultraviolet Balmer lines with wavelengths shorter than 400 nm. The number of these lines is an infinite continuum as it approaches a limit of 364.6 nm in the ultraviolet.>>

<<The name of the culture comes from the often parodied Baltimore accent and slang. "Hon" (/ˈhʌn/, an abbreviation of "Honey") was a common informal name for someone else. It is almost always used at the end of the sentence, e.g., "how bout dem O's, Hon?"* Baltimore's accent exemplifies a dialectal continuum between Tidewater American English, a southern American dialect, and Delaware Valley American English, a common coastal dialect, loosely possessing the vowel shifts of the former and general pronunciation of the latter.
For instance, "Baltimore" is pronounced "Balmer", and "Maryland" becomes "Merlin." Other common pronunciations include "ool", "amblance", "wooder", "warsh", "sharr or shaow", "far", "cowny", "tew", and "zinc" (oil, ambulance, water, wash, shower, fire, county, two, and sink respectively).[citation needed] There is also a popular summertime phrase, "goin' downy ayshin" (going down to the ocean, usually referring to Ocean City, Maryland) as well as popular phrases such as, "my (appliance) went up" (meaning died, shortened from "went up to heaven") and "dem O's" (i.e. "them O's", referring to the city's Major League Baseball team, the Baltimore Orioles).>>
