Hi

If I have a colour of R148 G27 B29 and I want that colour but as 20% transparent, what value would I need?  Is there a similar calculation?


Thanks!

    Multiply blend mode will do it.

      You can this by decreasing opacity percentage.

      I dont think I am explaining myself very well (or perhaps misunderstanding your answer?)

      The lighter red background in the image is the same red as the DRS logo, but it is set to 80% transparent.

      Another screen shot below.  So, the DRS logo I am actually going to use is white. But I need the transparent background to be the red of DRS (while maintaining its transparency).  To do this I imagine I need to start with a darker red.  Hopefully the below explains!

      You can't really do that in PS like in AI in ID, but you can lower the opacity of your brush or layers.

        Thanks! I'm actually working in Indesign, but I felt Photoshop may be more appropriate for colour issues.

        To be clear, I know how to set transparency to a colour.  Maybe an image would help.  So, in the image shown, the red of the DRS logo is the brand colour.  For the background of the website, I would like an image coming through it, so need to set the transparency (to 80%).  However of course as you can see it changes the colour.

        My question is, how do I find the value so I have the transparency but the colour is as per the brand colour of the logo?


        Thanks!

        If, with the Foreground color set to R149 G27 B29, you brought up the Color Picker you would see its Lab equivalent values. A change in the L (Lightness) value (it is currently 33 in a range of 0 to 100), will reduce or increase lightness only, discrete from color.  Its RGB equivalent will be displayed as you alter the L value.
