AAA3 (Aromantic Asexual Agender) Flag.
Here is a third 5-striped (pentastriped?) AAA design. Amber and Indigo come from merging the orangish & bluish sections of the popular “sunset” AroAce flag and tweaking them to be equidistant on the color wheel from agender’s central green stripe. This harmony creates a pleasing balanced design but the colors need some adjustment still. Symbolic meaning attributed to the colors from related flags could include:
Amber(-orange) - Aromantic spectrum, connection & community
Green - Agender spectrum, neutrality & unity
Indigo(-blue) - Asexual spectrum, perception & identity
Black - “A” - spectrum , integration & totality
Amber and Indigo are tertiary colors equidistant from green on the color wheel and blend into the neighboring hues orange and blue. These three equally spaced colors represent each of the A’s in the triple-A flag. The original aromantic flag had an amber/orange stripe which was later replaced with light green. Indigo is the complement to amber and is the neighboring color to violet which traditionally represents asexuality and could have a similar meaning here.
Expanding this basic 5 stripe form creates 9-striped and 7-striped versions.
IR(Black) | Amber | Yellow | Lime | Green | Cyan | Blue | Indigo | UV(Black)
Adding yellow, lime, cyan and blue make a gentle tertiary color gradient balanced on neutral green. Color theory wise, green is perfectly positioned as the central color as it is neutral - dividing warm colors from cool ones. Green is also holds the central position in royGbiv & other electromagnetic spectra.
Below is the 7-striped version with lime + yellow merged into chartreuse yellow and cyan + blue merged to azure blue.
IR(Black) | Amber | Chartreuse yellow | Green | Azure blue | Indigo | UV(Black)
This simplified version works as well as the 9 striped one in conveying balance and cohesion since the colors are equidistant and analogous.
I liken rainbow-like flags to electromagnetic spectra and usually add an infrared band above and an ultraviolet band below to indicate expansiveness and awareness of different modes of perception. This can be conflated with the black stripes of the agender flag. Plus the black just creates a nice aesthetic frame.
