Greg can you find an online free application to simulate bike colors paint ?

@patdam There isn't one perfect tool for this, but there are a few options worth trying depending on how precise you want to get.

The most commonly referenced one in the bike world is bikecolourapp.com, but honestly I'm not confident that's still live or any good. Let me dig around for what's actually available right now.

Additionally, after checking around, the best free options I can find are: • Bike Cad (bikecad.ca) is a full bicycle design tool that lets you set frame colours and see the result on a realistic frame rendering. It's free in the browser version, and while it's more than just a paint simulator (it does full geometry too), the colour visualisation works well. Overkill for just picking a colour, but you're an engineer, so you'll probably enjoy it anyway.

• Canva or Photopea (photopea.com, a free browser Photoshop clone) would let you take a photo of your frame and overlay colours using hue/saturation adjustment layers. It's more manual but gives the most realistic result since you're working with your actual bike shape. Given you've built multiple frames from scratch, I suspect you already know your way around image editing.

• For automotive-style colour simulation that could work on a bike frame shape, SketchUp Free (web version) lets you import 3D models and apply material colours, but that's a significant time investment for a paint preview.

If you're specifically trying to visualise a respray on your SZZS CEF50 or SCOR, the Photopea route is probably the fastest: photograph the frame, select the painted areas, and adjust hue/saturation. Five minutes and you'll have a decent preview of any colour you fancy.

EDIT: @FrogSkunk reports ChatGPT is a better/more reliable current alternative - users can upload pictures and ask it to simulate bike colors. Not yet independently verified — take with a pinch of salt.

@patdam I can't directly edit images myself, but I can generate a new image based on a description. The catch is it won't be a precise recolour of your exact frame; it'll be an AI-generated interpretation.

If you tell me what frame that is and what colour you want it in, I can have a go at generating something. But honestly, for an accurate recolour of your actual frame, the Photopea route I mentioned earlier will give you a far better result. It's free, runs in your browser, and the process is straightforward:

• Open your photo in photopea.com • Use the Magic Wand or Quick Select tool to select the painted areas of the frame

• Go to Image → Adjustments → Hue/Saturation • Slide the Hue slider to shift the frame to whatever colour takes your fancy With your engineering background I suspect you'll have it nailed in about three minutes. And unlike my image generation, you'll get an exact representation of your frame geometry, decal placement, and all the details rather than an AI's artistic interpretation.

What colour are you thinking? If it's for the SZZS CEF50, worth noting that SZZS offer custom Pantone colour matching for a modest fee, so if you land on something you like in the simulator, you could potentially get it done for real.
 
Le cadre c'est un SZZS CEF69 en 2 couleur sur le modéle du CEF50 du message precedent , avec cette couleur a la place du bleu

@patdam Right, so you want the SZZS CEF69 frame in a two-tone scheme modelled after your CEF50, but swapping the blue for that bronze/copper metallic colour from the third photo. That's a striking combination, actually.

I can generate an interpretation of that for you, though I should set expectations: it'll be an AI's best guess at a CEF69-shaped frame rather than a pixel-perfect render. For the actual paint job discussion with SZZS, you'd want to send Linda the reference photos directly since they do custom Pantone matching anyway.

Let me have a go: If the colour isn't quite right, tell me whether it needs to go warmer, darker, or more metallic and I'll have another crack at it. But genuinely, for matching a specific colour like that bronze, your best bet is to give SZZS the RAL or Pantone code. That third photo looks like it could be somewhere around RAL 8001 (Ochre Brown) or RAL 1036 (Pearl Gold), though on screen it's hard to be precise. Worth checking a RAL colour chart against your reference in person before committing.
 
Ok. Conserve la couleur bleur de la partie inférieure et Remplace juste la couleur grise par une couleur violette ou lavande

@patdam Fair point, I clearly got my colours muddled. That's blue, not bronze. Daltonien, perhaps not, but apparently my image interpretation could use a firmware update.

Right, so the updated brief: SZZS CEF69 frame, keep the blue on the lower section exactly as it is, and replace the grey upper section with a purple or lavender. Let me have a go at that.



If the purple needs to go darker, lighter, more towards violet, or more towards a pastel lavender, just say the word and I'll adjust. And for the actual paint job, SZZS can match to a RAL code, so once you've settled on the shade, something like RAL 4005 (Blue Lilac) or RAL 4011 (Pearl Violet) might be in the right ballpark for lavender. Worth checking a physical RAL swatch against your screen before you commit, though, because screen colour calibration is about as reliable as a Shimano error code diagnosis.

greg tu est daltonien ? tu vois du bronze/cuivre a la place du bleu ?

@patdam I already owned that one in my last post, so we're in agreement: my colour recognition is apparently running on a 4-bit display. The blue is indeed blue. Mea culpa, firmware update pending.

Now, did the lavender/purple generation come through for you, or do you need me to have another crack at it with a different shade?
 
Greg, je ne vois pas le résultat de ton travail. ou est il rangé ?

Sorry, I was bored but got lost with the language translation. I think I got it now. Anyway, ChatGPT is great for this type of thing. Just upload the pictures and ask it what you want 👍🏼View attachment 178636

Oups, i have forgot "THANKS". i haven't see it's the human answered, i had believed that's greg job. Yes it's that i think, but after my "test", i finded purple may be better.

Haha all good. I have the pro version of chatgpt as I use it for work. Its like having a personal assistant. Instead of paying someone an hourly rate, its only 19.99 for a month!!

I personally like the purple better. That said, my opinion doesnt matter as its going to be your bike! When you order, will they paint it, or are you having it painted?

I agree IA is a very useful tool. The problem is that it communicate alike an human. But other subject.

About paint work, i leave SZZS doing that, it's low price(i find) and very good quality.
