I designed my own version of the pastel ddlg flag,since i wanted to add more meanings to the colors,and i didn't really like the color pallete of the original one. I also didn't care for the order of the colors,and lack of identifying symbol.
Green safety,comfort,healing from being in Littlespace and cared for by daddy,harmony,growth in relationships
Blue: protection,loyalty,honesty,and wisdom from daddy,security,responsibility,trust,daddy dom's,patience
Yellow: joy,innocence,creativity,youthfulness, energy,communication which is large part of any healthy relationship but especially bdsm ones,pleasure
Purple: nostalgia,playfulness,not conforming to typical social norms for "how adults should act",and "how relationships should work"/stigmas around taboos, imagination,compassion,emotional enrichment,daddy's maturity
Pink: unconditional love,nurturing,little's,princesses,beauty,cuteness,roleplaying,kindness,affection,sweetness,dedication
As you can see,i really wanted to lean into the positive,romantic aspects of a proper,healthy fulltime ddlg dynamic relationship,rather than just the roleplaying,because those are just as important too.
