Some background: I am attempting to do some web design as a hobby. I am now at the point where I want to start introducing some texture to the site, and Tileables seems useful.
The readme in the Tileable packs states:
In this pack you should find a layered PSD file which contains each of the patterns in this pack on their own layer. I've included this so you can edit each pattern to your liking before defining a new pattern. You should also find the PAT pattern file which you should import into Photoshop. This is done via the layer styles menu when looking at the pattern overlay options. Finally, you have individual PNG tiles of the patterns so you can start using them in other applications.
I don't have Photoshop, so I downloaded GIMP (version 2.6.11). I have used neither before. I can't open the PAT file (error message: GIMP pattern plug-In could not open image), but I can open the layered PSD file. This gives me each Tileable as a layer.
The following step is to change the Tileable to match a colour in my palette. The colour I want to use is #f9efde, and its RGB value is 249, 239, 222. I have tried to play around in GIMP (specifically with the functions in the "Color" menu, such as "Color Balance", but this function seems to give me only the option of setting the percentage composition of colours in terms of the RGB and CMYK models. Where can I set the RGB value?
Thank you in advance.
