Change arrow colors in Bootstraps carousel

Question

I m obviously missing something stupidly simple here  I have images with a white background so I want to be able to edit the arrows on the Bootstraps Carousel so they are visible  So many changing the color of the arrows  NOT the background like I ve done     CSS   carousel-control-prev-icon   carousel-control-next-icon       height  100px      width  100px      outline  black      background-color  rgba 0  0  0  0 3       background-size  100   100       border-radius  50       border  1px solid black      Carousel HTML   lt div class    col-md-9  gt        lt div id  carouselExampleIndicators  class  carousel slide  data-ride  carousel  gt            lt ol class  carousel-indicators  gt               lt li data-target   carouselExampleIndicators  data-slide-to  0  class  active  gt  lt  li gt               lt li data-target   carouselExampleIndicators  data-slide-to  1  gt  lt  li gt               lt li data-target   carouselExampleIndicators  data-slide-to  2  gt  lt  li gt           lt  ol gt            lt div class  carousel-inner  role  listbox  gt               lt div class  carousel-item active  gt                   lt img class  d-block img-fluid  src  carousel Bars 20and 20Dots jpg  alt  First slide  class    img-responsive  gt               lt  div gt                lt div class  carousel-item  gt                   lt img class  d-block img-fluid  src  carousel murial jpg  alt  Second slide  class    img-responsive  gt               lt  div gt                lt div class  carousel-item  gt                   lt img class  d-block img-fluid  src  carousel Upper 20Partialism 20album 20covers004white jpg  alt  Third slide  class    img-responsive  gt               lt  div gt           lt  div gt            lt a class  carousel-control-prev  href   carouselExampleIndicators  role  button  data-slide  prev  gt               lt span class  carousel-control-prev-icon  aria-hidden  true  gt  lt  span gt               lt span class  sr-only  gt Previous lt  span gt           lt  a gt            lt a class  carousel-control-next  href   carouselExampleIndicators  role  button  data-slide  next  gt               lt span class  carousel-control-next-icon  aria-hidden  true  gt  lt  span gt               lt span class  sr-only  gt Next lt  span gt           lt  a gt        lt  div gt    lt  div gt

I too had a similar problem  some images were very light and some dark  so the arrows didn t always show up clearly so I took a more simplistic approach   In the modal-body section I just removed the following lines        lt  -- Left and right controls -- gt       lt a class  carousel-control-prev  href   id  data-slide  prev  gt          lt span class  carousel-control-prev-icon  gt  lt  span gt       lt  a gt       lt a class  carousel-control-next  href   id  data-slide  next  gt         lt span class  carousel-control-next-icon  gt  lt  span gt       lt  a gt    and inserted the following into the modal-header section       lt  -- Left and right controls -- gt       lt a  href   gamespandp  data-slide  prev  class  btn btn-outline-secondary btn-sm  gt  amp  10094  lt  a gt       lt a  href   gamespandp   data-slide  next  class  btn btn-outline-secondary btn-sm  gt  amp  10095  lt  a gt    The indicators can now be clearly seen  no adding extra icons or messing with style sheets  although you could style them however you wanted   See this demo image

a little example that works for me       carousel-control-prev       carousel-control-next          height  50px          width  50px          outline   color-white          background-size  100   100           border-radius  50           border  1px solid  color-white          background-color   color-white              carousel-control-prev-icon            background-image url  data image svg xml charset utf8  3Csvg xmlns  http   www w3 org 2000 svg  fill   23009be1  viewBox  0 0 8 8  3E 3Cpath d  M5 25 0l-4 4 4 4 1 5-1 5-2 5-2 5 2 5-2 5-1 5-1 5z   3E 3C svg 3E             width  30px          height  48px             carousel-control-next-icon            background-image  url  data image svg xml charset utf8  3Csvg xmlns  http   www w3 org 2000 svg  fill   23009be1  viewBox  0 0 8 8  3E 3Cpath d  M2 75 0l-1 5 1 5 2 5 2 5-2 5 2 5 1 5 1 5 4-4-4-4z   3E 3C svg 3E            width  30px          height  48px

You should use also   lt span gt  lt i class  fa fa-angle-left  aria-hidden  true  gt  lt  i gt  lt  span gt  using fontawesome  You have to overwrite the original code  Do the following and you ll be free to customize on CSS    lt a class  carousel-control-prev  href   carouselExampleIndicatorsTestim  role  button  data-slide  prev  gt       lt span gt  lt i class  fa fa-angle-left  aria-hidden  true  gt  lt  i gt  lt  span gt       lt span class  sr-only  gt Previous lt  span gt   lt  a gt   lt a class  carousel-control-next  href   carouselExampleIndicatorsTestim  role  button  data-slide  next  gt       lt span gt  lt i class  fa fa-angle-right  aria-hidden  true  gt  lt  i gt  lt  span gt       lt span class  sr-only  gt Next lt  span gt    lt  a gt      The original code   lt a class  carousel-control-prev  href   carouselExampleIndicators  role  button  data-slide  prev  gt       lt span class  carousel-control-prev-icon  aria-hidden  true  gt  lt  span gt       lt span class  sr-only  gt Previous lt  span gt   lt  a gt    lt a class  carousel-control-next  href   carouselExampleIndicators  role  button  data-slide  next  gt       lt span class  carousel-control-next-icon  aria-hidden  true  gt  lt  span gt       lt span class  sr-only  gt Next lt  span gt   lt  a gt

Currently Bootstrap 4 uses a background-image with embbed SVG data info that include the color of the SVG shape  Something like    carousel-control-prev-icon   background-image url  data image svg xml charset utf8  3Csvg xmlns  http   www w3 org 2000 svg  fill   23fff  viewBox  0 0 8 8  3E 3Cpath d  M5 25 0l-4 4 4 4 1 5-1 5-2 5-2 5 2 5-2 5-1 5-1 5z   3E 3C svg 3E        Note the part about fill   23fff  it fills the shape with a color  in this case  fff  white   for red simply replace with  f00  Finally  it is safe to include this  same change for next-icon     carousel-control-prev-icon  background-image  url  data image svg xml charset utf8  3Csvg xmlns  http   www w3 org 2000 svg  fill   23f00  viewBox  0 0 8 8  3E 3Cpath d  M5 25 0l-4 4 4 4 1 5-1 5-2 5-2 5 2 5-2 5-1 5-1 5z   3E 3C svg 3E

I know this is an older post  but it helped me out  I ve also found that for bootstrap v4 you can also change the arrow color by overriding the controls like this    carousel-control-prev-icon    background-image  url  data image svg xml charset utf8  3Csvg xmlns  http   www w3 org 2000 svg  fill   23fff  viewBox  0 0 8 8  3E 3Cpath d  M5 25 0l-4 4 4 4 1 5-1 5-2 5-2 5 2 5-2 5-1 5-1 5z   3E 3C svg 3E    important      carousel-control-next-icon     background-image  url  data image svg xml charset utf8  3Csvg xmlns  http   www w3 org 2000 svg  fill   23fff  viewBox  0 0 8 8  3E 3Cpath d  M2 75 0l-1 5 1 5 2 5 2 5-2 5 2 5 1 5 1 5 4-4-4-4z   3E 3C svg 3E    important      Where you change fill   23fff  the fff at the end to any hexadecimal value that you want  For example   fill   23000  for black  fill   23ff0000  for red and so on  Just a note  I haven t tested this without the  important declaration
