Recolour in photoshop. Need H over 180.

hans gruber · 14 Jul 2023 at 18:30

I'm trying to recolour a simple png image in photoshop. I have to input HSL values. I converted RGB to HSL and need a H value of 225, but photoshop will only let me use up to 180.

What am I doing wrong?

I think photoshop considers Hue, H, to be a 360° scale starting at 0 for your starting hue, which it allows you to adjust either +180° or - 180°.

So what would 225 be in photoshop terms?

I moved the slider from -180 to +180 to try and match the colour and despite S and L being the same none of the colours appear to match.

Col is
4960A4 blue
rgb(73, 96, 164)
hsl(225, 38%, 46%)

Gonna need more context for what you mean.

Hue is relative number based on the starting colour.

If you want to be 225° on from the zero point, then maybe -135° will get you what you want.

If you put the rgb into here https://www.rapidtables.com/convert/color/rgb-to-hsl.html it shows the correct colour and gives hsl values. I'm trying to covert a light pink logo to this colour.

When using the recolour option in photoshop no value for H for the above values matches the colour. H of -135 (S 38 and L 46) gives a light blue. Mucking about -104, -53, 3 comes close, but these are just values I have found messing about.

Is there anyway to be able to use rgb values, or an online tools I can use?

Try making the image greyscale first (simple desaturate is probably OK for this purpose)

I'm getting there now. In the recolour window you can click on the colour box next to hsl and then it lets you enter rgb or hex values.

I only use photoshop occasionally, so every time I do I have relearn how to do stuff.
