Shift to any shade

Question

Programming

In general, such a task. I've been thinking for 2 days now.

There is a drawing in vector format. Suppose sinebely:
# 94723f
# d6ae84
# cea47a
# e1ba8e
# 96764c
# e2b697
# c19a6d
# c19a6d
# a07b5f
# b79161
# bc8e6f
# a27357
# dcb88f
# 8d6c4d
# c79c76
# 5c3e2f
# 997551
# 503626
# a67962
# cea778
# dab68c
# e0ae8c
# bd9071
# ac885a
#aa7c63
#f1cca3
#864c3f
#b79264
#b79264
#886952
#deb78a

Here is the color list.

You need to convert this picture to a red tint:
I.e. dark blue turns into dark red, blue into pink, etc.

Likewise for other colors. I think someone has already done this. Interested in source code or algorithm. I'm just really bad with flowers.

I would be grateful for an answer.

Answer 1

Everything is bad with colors, too, but why not translate it into HSL and play around with the values, realizing what you need?

Answer 2

You can try tweaking the red channel. For example. red=(255+red)/2

Answer 3

The most correct thing, of course, is to convert to HSL, and change the Hue value (it’s even called “color shade”).
Formulas can be found here on Wikipedia .

Answer 4

If Javascript, then use the RGB to HSL conversion function - mjijackson.com/2008/02/rgb-to-hsl-and-rgb-to-hsv-color-model-conversion-algorithms-in-javascript
And then shift the HSL Hue channel to the desired value, and then convert HSL back to RGB.
