The blue bumper sticker with two yellow stripes is the logo of the Human Rights Campaign, or HRC. It stands for equality in the lesbian, gay, transgender and bisexual community. Today, the logo is seen on bumper stickers, Facebook walls, t-shirts, business cards and more. It is a way of raising awareness of HRC's fight for human rights.
The blue and yellow equality logo was introduced by the Human Rights Campaign Fund in 1995. It was part of a new era for HRFC -- an era in which the organization strove to reach mainstream advocacy for the LGBT community. Today, the Human Rights Campaign as it is now known, is the largest LGBT advocacy group in the nation. This success is partially due to the popularity of the blue and yellow logo, which can be seen plastered on social media sites, cars and clothing not just in the United States but also in Canada.
There is a large amount of symbolism embodied in the HRC's equality logo. The equals sign stands for the true equality that the campaign seeks for all humans regardless of gender, race or any other factor. The colors were chosen because they were bold and looked strong, much like the strength found inside the HRC's members and supporters.
