T-shirt colour guide with RB conversion (Updated 22nd May)

Chris  Wahl Chris Wahl 191 posts

I’ve made the following chart to help take the guess work out of how your t-shirt designs colours will look after Red Bubble’s colour conversion.

I simply took a CMYK swatch palette from Photoshop and put it on a t-shirt in Redbubble. As a result, all the colours were converted.

Update 22nd May- Additionally, I’ve now added coordinates on the colour grids to make it easier to find corresponding colours between palettes and remember them for future use.

-In the first block of swatches is an extensive range of CMYK colours which you can use while in RGB to colour your designs. On the bottom is how these colours will be converted on RB’s shirt design preview.

For a larger version of the colour guide you can go here (copy and paste in your browser)-

Wow Chris, you are a pro. It’s clearly not luck that your stuff is so good. You put so much thought and work into it, and this is a clear example of how precise you are with your work.

I mean – I barely spend any thought on colour – and now, you’ve made it even easier for dopes like me to get it right.

Thanks.

Why does redbubble have a colour conversion? I’m not a happy camper.

The RB printers use sRGB colour profiling, if I recall correctly. Most digital printers use this colour space.

Hipnrad- It’s not so much a colour conversion as it is a virtual approximation of how it might look once printed on cotton.

Hi Chris!

Really useful. Will study this.

Can you help me with something? I’ve received a tee but the black areas are NOT black – they appear a dark purply-brown. Okay, the image is on claret fabric but I don’t understand why black is not black. Is it a property of the ink (slightly translucent) or the way it sits on the fabric? The whites are white.

Opened my image in PS and ran Color Picker over it – black values R0 G0 B0
Scanned my tee and black values are R51 G37 B31

Is it something I’m doing? Or is there anything I can do to get black blacks?

Hope you can help.

I’m guessing it’s something to do with the printing / inks. What coloured shirt did you print on? If they were using CMYK you could specify a true black as 100%K (or perhaps something richer like 40/40/40/100?) but it’s a bit of a worry when they specify RGB then don’t print true black…
